RV042 bandwidth management issues

I am trying to set up my router to grant http traffic a minimum banwidth of - for example - 5,000 kBit (if there is any http traffic).
So I set http min. rate to 5,000 while I set nntp min. rate to 1 (see enclosed screen shot)
However, when I run nntp downloads on several connections (e.g. 10) my single http download never goes above 1,000 kBit. Without any other connections I reach 8,000 kBit.
Btw. I am using a single 12 MBit line.
What is wrong?
Thank you for your help!

I am looking at your setting and it seems that the router is functioning properly. It has a lot of other factors that you are not thinking about also. If you do a speed test what are the speeds that you are getting? If you move the router out of place and do the same time what are the down load speeds that you are getting?
Also I see that when you have only the single one downloading you want to get the speed for the max bandwidth that you have selected. If you down load this same file with the router not in place do you get the same out come? If it is different how much difference are you getting? Most of the time if your max download speed is 10 to 12 Meg, you will get roughly a third of that when downloading files. You must depend on the device at the other end also.
What were you getting before you created any of these rules?
Thanks

RV320 Bandwidth Management issue

Hello,
we use RV320 (firmware v1.1.0.09) since 2 months as Dual-WAN-Gateway in Load Balance Mode :
WAN-1 – TV-cable with 6 Mbit/ 100 Mbit (up/down);
WAN-2 – ADSL 600 Kbit/ 6 Mbit (up/down).
We need ADSL for some VPNs because the TV-cable provider can't supply us with a static IP.
The QOS settings are simple : rate control - min / max rates for up / downstream.
We have following bandwidth settings :
WAN1 Upstream min 500 Kbs max 5000 Kbs
WAN1 Downstream min 5000 Kbs max 50000 Kbs
WAN2 Upstream min 80 Kbs max 500 Kbs
WAN2 Downstream min 500 Kbs max 5000 Kbs
The problem is – the rv320 uses WAN2-bandwidth limitations for WAN1 too !
Is this a bug or feature ?
Best regards.

I have the problem too, but discovered it happens with Safari on Mac. Using FireFox on Mac (OS X 10.10) the necessary UI elements do appear.

RV042, Load Balance issue

Hello,
I'm a newbie to routers and on this discussion.
I've purchased a Linksys RV042 hoping I could connect my two ISP.
Both of them are 1/1 Mb, first is DSL second PPPoE connection.
The problem is that on system summary page it doesn't show me that second WAN is connected. Even when I trying to manually connect to Internet it doesn't help.
When this connection is in Load balance Mode, internet is very slow, sometimes it's even disconnected.
My question is:
How to configure Load Balance properly?
I've tried this page:
http://www.cisco.com/en/US/products/ps9923/products_qanda_item09186a0080a36632.shtml
but it didn't helped.
Or maybe it's just a demo of this option and doesn't work at all?
Thanks for the reply.....

Eliviszopa,
Hi. My name is Tiya and I am one of the Cisco SMB Support Engineers. I have been eyeing your post and I would like to add a few recommendations.
From what I've gathered, you are having an initial problem with your Dual-WAN configuration, in that you are unable to have both WAN interfaces Live at the same time. I will list a few things that will help you in determining if there is an issue with your RV042's Dual-WAN configuration and connectivity.
I understand your Network Topology to be: [ISP Modem 1 & ISP Modem 2]---->RV042---->LAN Clients (PC).
First thing, we need to ensure your router it at the most current firmware version for optimal performance. The RV042 series routers are currently in their 3rd HW revision, so we also need to ensure we download the firmware that is compatible with the HW version of your RV042
To locate HW version:
Look on the bottom of your RV042.
You will find the Serial Number and MAC      address sticker.
The HW Version will be visible by the      Model Number on that sticker.
Image below has a Red Square around the      Model Number and HW version of an older RV042 as a reference. HW is indicated      with 'v' and rational number, i.e. v1.1, v2.0. Your sticker may look      slightly different, but the content will be the same:
Now that we are certain of the HW version, check the release notes below to check the best firmware version for your RV042. I have provided a link below to the RV042 Release Notes:
Firmware v 4.0.0.7 Release Notes:      http://www.cisco.com/en/US/docs/routers/csbr/rv0xx/release/rv0xx_rn_v4-0-0-7.pdf
Firmware v 1.3312.19-tm Release Notes:      http://www.cisco.com/en/US/docs/routers/csbr/rv042/release/notes/RV042_RN_v1-3-12-19-tm.pdf
If your RV042 is using neither of the 2 firmwares, follow this link to download the correct version for your router:
http://www.cisco.com/cisco/software/type.html?mdfid=282414010&flowid=784
I would recommend you download and      'flash' your RV042 with the current compatible version of firmware to      address the possibility of software corruption.
Now, we need to reset your RV042 to factory defaults to remove any parameters previously configured and also, in essence, clear the router's memory so that we can start afresh. When this happens, your RV042 will return all settings to their default state; in other words, it will be as if you are pulling it out of the box for a new install. To do this:
Disconnect the RV042 from your network,      so that the only item the RV042 is only connected to the power outlet.
Locate the reset button on your RV042.      This will be on the front of your router and it will be recessed a bit.
Use a small tipped item; paperclips      usually work best, to hold down the reset button for 30 secs. Anytime less      will not guarantee a full reset to factory defaults.
Connect your RV042 to your PC. After      about 30 secs, ensure that you have an IP address of 192.168.1.100 on your      PC.
Now, let's test each WAN port with each of your ISP connections.
The next few steps will take us through a process that will ensure both WAN ports are working, and ultimately will help is in determining your Dual-WAN connectivity performance.
Connect one of your DSL modems to WAN1 and configure the WAN1 interface accordingly:
· DSL connections typically are UN-bridged by default; where you will see the modem is performing NAT. You will use DHCP as the WAN tupe for UN-bridged DSL connection types. This UN-bridged state can be recognized quickly in a couple of ways.
o    There is a PRIVATE IP address displayed as the WAN1 IP address, e.g. 192.168.x.x. where X is a number 0-254, 10.x.x.x where X is a number 0-254, or less commonly, 172.16.x.x where X is a number 0-254.
o    When connecting to the modem directly to your PC, you are able to reach the Internet.
o    If your DSL connection is UN-bridged, you must make sure the LAN IP Subnet of your Modem and Router are NOT the same.
o    Again, you will use DHCP as the WAN type for UN-bridged DSL connection types.
· DSL connection that is Bridged will require a PPPoE Username AND Password. This PPPoE username and password will be entered on the RV042 under the WAN type PPPoE. PPPoE connections can be quickly recognized in the same manner:
o    There is a PUBLIC IP address displayed as the WAN1 IP address AFTER correctly configuring WAN interface to use PPPoE and using correct UN/PW.
o    You are NOT able to reach the Internet when connecting your PC directly to your RV042.
· Contact your ISP to assist you in determining the bridged state of your modem to be absolutely certain.
2.     After you have properly configured WAN1 and confirmed Internet connection, configure WAN2 in the same fashion.
3.     Change Primary WAN to WAN2 by going to the following location in the RV042:
· System Management>Dual-WAN> Smart-Link Backup Primary : WAN2 (change this option)
4.     Disconnect DSL Modem from WAN1 and connect to WAN2.
5.     Power cycle the DSL Modem, RV042, and also disconnect your PC from the router as well while it is powered down.
6.     After about 5-10 sec, and in this order, power on your Modem, power on you RV042, and reconnect your PC to one of the LAN ports of your RV042
7.     After about 30-60 secs, test for Internet connectivity.
Now we will do the same for your other ISP connection.
1.     Disconnect all devices from the RV042, save your PC.
2.     Change Primary WAN to WAN1 by going to the following location in the RV042:
· System Management>Dual-WAN> Smart-Link Backup Primary : WAN1 (change this option)
3.     Connect 2nd ISP connection to WAN1 and configure according to Modem configuration, either DHCP or PPPoE.
4.     Power cycle the DSL Modem, RV042, and also disconnect your PC from the router as well while it is powered down.
5.     After about 5-10 sec, and in this order, power on your Modem, power on you RV042, and reconnect your PC to one of the LAN ports of your RV042
6.     After about 30-60 secs, test for Internet connectivity.
7.     Do the same for WAN2 using your 2nd ISP connection
At this point, we should now know for certain if both WAN Interfaces will allow Internet connectivity.
If you have problems with these steps, repost with the steps you took and the results.
If things are OK, then we will continue with configuring the router for Load Balance Mode:
1.     Navigate to System Management>Dual-WAN and change your selection from Smart-Link Backup to Load balance
2.     Configure both WAN1 and WAN2 with the configuration that correlates to the Modem connection it will receive.
3.     Connect both Modems to the correct WAN port on the RV042.
4.     Power cycle all devices; Both Modems, RV042, and PC
5.     Navigate to RV042 management page and check to see if there are IP addresses for WAN1 & WAN2 Interfaces.
If you have problems with these steps, repost with the steps you took and the results. Let us know your results.

LRT214 - Bandwidth Management Rate Control Rule

I have an LRT214 that is configured with 3 VLANs. VLAN 1 just for management, VLAN 10 for internal devices, VLAN 20 for guest devices. Everytime i try to add Bandwidth Management Rate Control Rules for my VLAN 20 IP Range, the router stops responding within 10 seconds to 5 minutes. If I remove the rules, I am able to keep the network up for days. I have even had someone from Linksys Support remotely login to my computer then the router and remove my rules, then add them just like I had. It stayed up for about 3 minutes and then I lost network connections to all devices and couldnt even login to the router. Once I power cycle the router, i am able to get into the router long enough to remove the rules and then everything functions normally. Is anyone else having issues with Rate Control Rules or are there other steps that need to be done as well?
Just as an FYI, I do have an open case with Linksys but havent heard back from them since Wednesday the 21st. I have tried configuring another LRT214 and even a LRT224, the same issue happens when I add the rules on both of those as well.

QOS does a calculation based on the up\down Maximum bandwidths. Then applies that against the rules you set. It's critical that the values be accurate.
Rate control is like pie slices. Leave enough for the rest of the network.
Please remember to Kudo those that help you.

Bandwidth management on 3650 configuration example

in the 3650 datasheet, he says
The 3650 switch has advanced wired plus wireless QoS capabilities. It uses the Cisco modular QoS command line interface (MQC). Theswitch manages wireless bandwidth using unprecedented hierarchical bandwidth management starting at the per-access-point level and drilling further down to per-radio, per-service set identification (SSID), and per-user levels. This helps manage and prioritize available bandwidth between various radios and various SSIDs (enterprise, guest, and so on) within each radio on a percentage basis. The switch is also capable of automatically allocating equal bandwidth among the connected users within a given SSID. This makes sure that all users within a given SSID get a fair share of the available bandwidth while being connected to the network. The UADP ASIC enables the hierarchical bandwidth management and fair sharing of bandwidth, thereby providing hardware-based QoS for optimized performance at line-rate traffic.
In addition to these capabilities, the switch is able to do class of service (CoS) or differentiated services code point (DSCP) based queuing, policing, shaping, and marking of wired plus wireless traffic. This enables users to create common policies that can be used across wired plus wireless traffic. The 3650 also supports downloadable policy names from the Cisco Identity Services Engine (ISE) when a user successfully authenticates to the network using the ISE.
We are having repeated issue of a single user taking up all the WAN bandwidth. We are trying to figure out a way to limit the user from taking up all the bandwidth My leadership see the datasheet and attended the webinar and they mention bandwidth management and think that the 3650 is the solution. From wireless, maybe, but from wired, ???
How could accomplish this goal from a wired side? or should I take a different approach?
I can discuss further if needed.

Hello,
That's a question that you as the network admin of that organization could answer.
How much traffic for business purposes must travel via HTTP/HTTPS?
How much bandwith are you willing to provide to this 2 protocols?
Those are the kind of answers you need to answer before setting the number

The Ultimate Guide to Resolving Profile and Device Manager Issues

The following article also applies to issues after re-setting the severs' hostname. It also applies to situations where re-setting the Code Signing Certifictateas described by Apple has not resolved the issue.
Hello,
I have been plagued with Profile Manager and Device Manager issues since day one.
I would like to share my experience and to suggest a way how to resolve issues such as device cannot be enrolled or Code Signing Certificate not accepted.
I shall try to be as brief as possible, just giving an overview of the steps that resolved my issues. The individual steps have been described elsewhere in this forum. For users who have purchased commercial SSL certs the following may not apply.
In my view many of these issues are caused by missing or faulty certificates. So let us first touch on the very complex matter of certificates.
Certificates come in many flavours such as CA (Certificate Authority), Code Signing Certificate, S/MIME and Server Identification.
(Mountain?) Lion Server creates a so-called Intermediate CA certificate (IntermediateCA_hostname_1") and Server Identification Certificate ("hostname") when it installs first. This is critical for the operation of many server functionalities, including Open Direcory. These certs together with the private/public keys can be found in your Keychain. Profile and Device Manager may need a Code Signing Certificate.
The most straightforward way to resolve the Profile Manaher issues is in my view to reset the server created certicates.
The bad news is that this procedure involves quite a few steps and at least 2 hours of your precious time because it means creating a fresh Direcory Master.
I hope that I have not forgotten to mention an important step. Readers' comments and addenda are welcome.
I shall outline a sensible strategy:
1. Clone your dysfunctional server to an external harddrive (SuperDuper does a reliable job)
2. Start the server fom the clone and shut down ALL services.
3. It may be sensible to set up a root user access.
4. Back-up all user data such as addess book, calendar and other data that you *may* need to set up your server.
5. Open Workgroup Manager and export all user and workgroup accounts to the drive that you using to re-build your server (it may cause problems if you back-up to an external drive).
6. Just in case you may also want to back-up the Profile Manager database and erase user profiles:
In Terminal (this applies to Lion Server - paths may be diferent in Mountain Lion !)
Backup: sudo pg_dump -U _postgres -c device_management > $HOME/device_management.sql
Erase database:
sudo /usr/share/devicemgr/backend/wipeDB.sh
7. Note your Directory (diradmin) password for later if you want to re-use it.
8. Open Open Server Admin and demote OD Master to Standalone Directory.
9. In Terminal delete the old Certificate Authority
sudo rm -R /var/root/Library/Application\ Support/Certificate\ Authority/
This step is crucial because else re-building you OD Master will fail.
9. Go back to Server Admin and promote the Standalone Directory to OD Master. You may want to use the same hostname.
10. When the OD Master is ready click on Overview and check that the LDAP and Keberos Realm reflect your server's hostname.
11. Go back to Workgroup Manager and re-import users and groups.
NOTE: passwords are not being exported. I do not know how to salvage user passwords. (Maybe passwords can be recovered by re-mporting an OD archive - comments welcome! ).
12. Go to Server App and reset passwords and (not to forget) user homefolder locations, in particular if you want to login from a network account!
If the home directory has not been defined you cannot login from a network account.
13. You may now want to restore Profile Manager user profiles in Terminal. Issue the following commands:
sudo serveradmin stop devicemgr
sudo serveradmin start postgres
sudo psql -U _postgres -d device_management -f $HOME/device_management.sql
sudo serveradmin start devicemgr
14. You can now switch back on your services, including Profile Manager.
In Profile Manager you may have to configure Device Management. This creates a correct Code Signng Certicate.
15. Check the certificate settings in Server App -> Hadware -> Settings-> SSL Certificates.
16. Check that Apple Push Notifications are set.(you easily check if they are working later)
17. You may want to re-boot OS Server from the clone now.
18. After re-boot open Server App and check that your server is running well.
19. Delete all profiles in System Preferences -> Profiles.
19. Login to Profile Manager. You should have all users and profiles back. In my experience devices have to be re-enrolled before profiles can be pushed and/or devices be enrolled. You may just as well delete the displayed devices now.
20. Grab one of your (portable) Macs that you want to enrol and go to (yourhostname)/mydevices and install the server's trust profile. The profile's name should read "Trust Profile for...) and underneath in green font "Verified".
21. Re-enrol that device. At this stage keep your finger's crossed and take a deep breath.
22. If the device has been successfully enrolled you may at last want to test if pushing profiles really works. Login to Profile Manager as admin, select the newly enrolled device. Check that Automatic Push is enabled (-> Profile -> General). Create a harmless management profile such as defining the dock's position on the target machine. (Do not forget to click SAVE at the end - this is easily missed here). If all is well Profile Manager will display an active task (sending) and the dock's position on the target will have changed in a few seconds if you are on a LAN (Note: If sending seems to take forever: check on the server machine and/or on your router that the proper ports are open and that incoming data is not intercepted by Little Snitch or similar software).
Note: if you intend to enrol an Apple iPhone you may first need to install the proper Apple Configuration software.
Now enjoy Profile and Device Manager !

Twistan

HI
1. In Action profiles, logon to system and recheck correcion are available in action definition as well in condition configuration and the schedule condition is also maintained. but the display is not coming(i.e in the worklist this action is not getting displayed).
You can check the schedule condition for the action and match the status values...or try recreating the action with schedule condition again....for customer specific ....copy the standard aciton with ur zname and make a schedule condition and check the same.
2, In suppport team of incident when i give individual processor it throwing a warning that u r not the processor. but when i give org unit it is working perfectly. Could anyone guide on this.
You need to have the empolyee role for BP ..goto BP and got here dropdown for ur bp and choose role Employee and then enter ur userid
also make sure that u have the message processing role

Power Mac G5 DP1.8GHz - Bad Logic Board or Power Management Issue?

I have a Power Mac G5 DP1.8GHz/1.5GB/80GB which I bought non-working. It has not yet been disassembled or examined by a certified tech. This is it's issue (which replicates): the computer powers on. It makes a single warning tone, then the LED flashed at least 15 times (too fast to count). Then the posting chord is heard. Hard drive spins up. Then nothing (no video). Won’t boot from any disk. I have changed the RAM and tested the RAM banks with known-to-be-good RAM from another DP1.8GHz G5. The warning tone stopped once or twice after this switch, but then it didn’t chime. I changed the PRAM battery, but not with as new one. However, after installing the used one and then resetting the PMU, it displayed video briefly for the first time. While installed in the other 1.8GHz G5, the hard drive was formatted, given a clean install of OS X 10.4.11, and then moved into this computer where is never mounts. The computer is not accessible through TDM.
Do I have a bad logic board? Bad CPUs? A power managment issue? A RAM issue?

Through my own trial and error troubleshooting, I have found the CPUs to be in good working order and the logic board passes the Apple Service Diagnostic every time. Despite the installation of numerous pairs of modules that worked in another DP1.8GHz, the computer has a RAM issue-it gives the "no good RAM" tone most of the time when it powers up (after a PMU reset it does not). Also the computer boots from disk or into Open Firmware but the disk utility can't see either hard drive so I may have a bad SATA controller.

Color Management issues with Illustrator

Can someone help me figure out the color management issues I'm getting when printing on an Epson 3880 from Illustrator?
The image comes out severely red as evident on the face. I'm not getting the same problem when printing from Photoshop, even though I set same paper profile in printing dialog box.
I attached two printed picture (one from Photoshop CC, and one from Illustrator CC) that I took with my iphone so that you can see the printed result. Even when I try to simulate same thing using illustrator soft proofing process, the soft proof does not show me anything close to how it gets printed out. And I tried all device simulations to see if any would match it. Im using CMYK SWOP v2 for Color space in both programs.

Dougfly,
Only an hour wasted? Lucky you. Color is an incredibly complex subject. First, forget matching anything to the small LCD on the back of your camera. That's there as a basic guide and is affected by the internal jpg algorithm of your camera.
2nd, you're not really takeing a color photo with your digital camera, but three separate B&W images in a mosaic pattern, exposed thru separate red, green and blue filters. Actual color doesn't happen until that matrix is demosaiced in either your raw converter, or the in-camera processor (which relies heavily on camera settings, saturation, contrast, mode, etc.)
Having said the above, you can still get very good, predictable results in your workflow. I have a few color management articles on my website that you might find very helpful. Check out the Introduction to Color Management and Monitor and Printer Profiling. In my opinion, a monitor calibration device is the minimum entry fee if you want decent color.

Charm - how manage issues after go live phase

Hi all,
ny customer use Charm Implementation project for managing roll-outs of new countries in his SAP ECC Landscape.
Now Test Phase is going to end and he asks himself: "how can I manage issues after go live in Charm?"
If I have to create additional TRs for bug fixing in the weeks after go-live can I manager them in Charm?
I know there is the function for create TR direct in Talsk List, is this the correct way?
In other words, do I manage issues after go-live out of Change Documents using Task list?
As you know, Is there any best practices from SAP od from elsewhere?
Thanks o lot
Giovanni Lippolis

Hi Miguel, Bob and Jansi,
thanks for you contributions.But I realize I didn't explained myself completly.
My situation is similar to what Bob described,
I'm not in an ideal world (do you remember Clint Eastwood and Kevin Costner), and I think neither you.
But, in my case there are not open TR to be recovered in project, but I suppose I'll have to open some TR (I hope a few) for fixing bug that will happen in production in the days post roll-out.
So I wouldn't like to manage there fix in a maintenance project, because the reason of these bugs is in TR imported in roll-out.
What I would like to do is to regress project to the Test phase (I don't need new CR and NC!) and open few Test Messages for fixing bugs.
I'suppost It should be possilble.In your opinion?
Ideas?
Thnks a lot.
Giovanni

Colour Management Issue with PS CS3 and Leopard 10.5.2

Hi Everyone,
Since I have installed Leopard I am having colour management issues with Photoshop CS3 and my Canon i9950 printer.
My screen is calibrated with a Spyder and I used to ask Photoshop (in 10.4.11) to manage colour when printing and used the Spyder profile. Everything came out as I saw it on screen.
Now in leopard when I do the same thing everything comes out too yellow on the print. If I ask Photoshop to let the printer manage the colour it is too red. If I use the default colour management (photoshop managing the colour and it choosing the colour space it is better, but still too yellow).
Photoshop gives the hint to turn off colour management in the printer but there is no option for this and it also said the same thing before of course (when it worked in 10.4.11).
Any ideas?
Thanks.

>It was working perfectly in Tiger with the monitor profile.
You were lucky.
the monitor profile is so Photoshop can display your images correctly.
the working space is Adobe RGB, sRGB, BruceRGB, ect... these are all known color spaces so when the file goes to another computer there is a consistent color space for reference. If you use your monitor profile as a working space then nobody else knows what is going on with your file.
when you print you need to use the printer profile for the type of paper you are printing on this is supplied by the printer manufacturer. you can also have custom profiles made.
you need to read up on color management:

You need to use the correct printer profile for the paper you're using. If the printer didn't come with any pre-built profiles, check Canon's web site to see if they have any profiles available for your printer that you can download.
Printer profiles are very specific. You can't take take a profile for glossy Epson paper and expect it to work very well for Canon glossy paper.

I'm having exactly the same problem, only my printer is a Canon Pixma iX4000. The colour is all bleached out, it looks exactly like when you've accidentally printed an RGB file on a CMYK printer, and at first I thought that was what I had done, but it isn't. This is very frustrating, I've spent all day going through the manuals, recalibrating etc, but no luck. This is a brand new Mac Pro and printer, but if its not going to print what I see on screen it's just expensive junk.
I wasn't sure if the problem was Leopard or the printer or CS3...

Bandwidth Management for Software

Is there a utility out there that would allow you to allocate specific amounts of bandwidth any software could use? In many download managers (such as Speed Download, Limewire, Azul, etc.) you can easily set the total amount of bandwidth and even per file download parameters. I have always been surprised that browsers such as Safari and even iTunes does not allow you to control the amount of bandwidth it is to use when downloading.
I often find myself in situations where I need to download a large file, and yet be able to continue to surf for example, or else I would like to keep the setting in my iTunes to download podcasts automatically when I launch it. Both Safari and iTunes, will take as much bandwidth as you can throw at them which means that it can grind every other on line activity to a halt (specially when you do not have a blazing fat connection).
Anyone know of any such software?
Thanks.

Thanks, but I don't understand what this has to do with bandwidth management? Perhaps I do not understand the capabilities of nice, but isn't nice just a way to prioritize applications and services? How would you use it to allocate bandwidth?
By giving various jobs different priorities, the effective bandwidth is limited. If you use 100% of the bandwidth for 1% of the time and 0% of the bandwidth for 99% of the time, you are effectively giving the "niced" app only 1% of your bandwidth. And since a computer is digital, there is really no such thing as "instantaneous" bandwidth, as there is in other areas of communication.
If you have 10 processes running and each consumes 10% of your total bandwidth, it does not matter whether the processes are time-shared or bandwidth-limited, when considered over any reasonable period of time.

WARNING: Canon Pro Printers and CS4 – Serious Colour Management Issue

Over the last four days (and over fifty prints) I have undertaken extensive and meticulous tests to identify the cause of a problem; namely that targets for profiling a new printer (a Canon Pro9000), printed with ‘no colour management’, were printing far too dark and with what appeared to be a colour cast.
I have conclusively eliminated the printer, the printer drivers, the Mac OS, corrupted preference files, corrupted user accounts, incorrect Photoshop settings, incorrect printer driver settings, the ‘sticky settings' issue, and user error as possible causes of the problem.
I can say with 95% certainty that my tests, conducted using Mac OSX 10.4.11, have proved the following:
That, printing to a Canon Pro9000 or iP4500, Photoshop CS4 does not print accurate targets suitable for producing profiles. This applies to both the No Colour Management (NCM) and the Printer Manages Colour (PMC) settings.
Photoshop CS and CS2 are not effected.
I did not test CS3.
Furthermore, colour managed prints (using the same accurate profile made in CS2), printed in CS2 and CS4, show subtle differences. This may not be an issue except in the most critical applications.
It is likely that the problem will not be confined to the two Canon printers above since many other Canon printers share the same driver architecture.
Reading posts and discussions on other websites would seem to indicate that this problem is also manifest with some Epson printers and may also effect Mac OSX 10.5.
I have to conclude, therefore, that Photoshop CS4 cannot be replied upon to print targets of sufficient accuracy to produce reliable profiles for a colour managed workflow.
The fact that this is only just being reported can be attributed to four factors:
That many CS4 users are continuing to use profiles made under older versions of Photoshop and have yet to make new profiles using CS4.
Some users may not immediately notice a problem, or may ascribe it to other causes.
Some users may take the line of least resistance and use a previous version of Photoshop to work around the problem.
Some users are still using the older versions of Photoshop not effected.
Eric Chan (of Adobe) has stated on another website that CS4 implemented some new APIs for printing and that this has given rise to some "minor glitches". If Eric Chan is correct, and Adobe changed the APIs in Photoshop CS4, this begs question of whether Adobe sufficiently tested CS4 before release ? If Adobe did not test their software, and therefore failed to identify this critical problem, this would suggest negligence on Adobe’s part. If Adobe identified the problem but then did not inform users that a potentially serious colour management issue existed this would suggest wilful or gross negligence.
It is not good enough to say that Adobe simply followed the ‘conventional’ path and ‘followed the rules’ regarding API implementation. The experience of end users does not correspond to a “minor glitch” and, in my case, has been extremely costly in terms of time (over five days in all), lost revenues, and materials. Furthermore, why should Adobe's customers be forced to use their valuable time diagnosing problems clearly of Adobe's creation – and actually admitted.
In UK law providers of goods and services (and this includes software) have to supply them as “fit for purpose”. Clearly, in terms of colour management, CS4 is not fit for purpose. Neither can Adobe hide behind its labyrinthine licensing terms since any exclusions would be ruled unlawful under the UK’s ‘Unfair Contract Terms’ Act.
My strong and unequivocal recommendation is that representatives from Adobe, Apple, and the printer manufacturers meet together – with the utmost urgency – and provide a rapid and complete solution. It is simply not good enough to pass this ‘over the wall’ saying “it’s not our problem”. It is. Adobe's, Apple's, and the printer manufacturers'. Please solve it. And quickly.
Identify the problem clearly, make it and the solution/s public; and publicise it widely and thoroughly.

Dear DYP.
Thank you for your concern.
"What fixes have you tried?"
If I may quote from my post above:
"I have conclusively eliminated the printer, the printer drivers, the Mac OS, corrupted preference files, corrupted user accounts, incorrect Photoshop settings, incorrect printer driver settings, the ‘sticky settings' issue, and user error as possible causes of the problem.
I can say with 95% certainty that my tests, conducted using Mac OSX 10.4.11, have proved the following:

Photoshop CS and CS2 are not effected.
I did not test CS3"
These tests took place over three weeks and involved over five days of work and the replacement of the printer on Canon's recommendation (although the printer is clearly not at fault).
Please note that I am using Mac OSX 10.4.11.
"What driver versions are you using?"
Pixma iP4500 6.9.3 (also 6.9.1, 6.9.2 and the driver supplied on the CD).
Pro 9000 4.8.7 (also 4.7.3, 4.8.4 and the driver supplied on the CD).
"Yes it is frustrating but in a lot of cases it is fixable as I and others have clear reported, on this and the LR forums."
I have not found any fix on any website referring to Canon printers, despite exhaustive searches (this includes Canon's European and US websites which are mute on the issue).
The ReadMe file supplied with the installation disc of CS4 refers to problems with "some Canon printers" when printing with the 'Printer Manages Color' but does not identify using 'No Color Management' nor Epson printers as having issues.
I hope this post answers your questions.
Clearly all users of CS4 need to be warned of this problem which is likely to effect other printers. I believe that I am assisting others by issuing this warning. It is done, not to cause mischief, but in the spirit of a public service. CS4 users can then treat their printing results from CS4 with caution, and then conduct their own tests. I have presented a workaround which is to use a prior version of CS4.
