Print Pool Behavior

Hi
I've setup Print Pooling with 2 identical Konica Minolta bizhub C554e on Windows Server 2012 R2.
We have noticed that if both machines are available (not in use at all) all printjobs always goes to the same machine.
Only if this machine is busy with a large print job, the next job goes to the other one.
I have noticed that it seems that Print Pooling only works as expected during the time a machine is processing the job. When a large job has started printing, the next job will show up in the same queue, but of course we want the next job to print on the
other machine when the first one is printing (useful if many pages in the first job).
Do anyone know / can confirm this behavior? Possible to modify some settings?
The machines names in the print server are identical, just the last number is 1 and 2. Why is the server sending all jobs to number 2 if both are available every time? (Number 2 is the second check box in the ports list). Possible to set nr 1 as default?(either
want nr 1 as default due to where the physical location in the room is OR I want the server do randomly send to 1 and 2, not to nr 2 as default at least).
Can someone also confirm that Print Pool is only for print jobs (Print Pool doesn't understand if someone is using the machine to something else, for example just copying papers).
I have also 2 Print Queues to these same machines, both queues as Print Pools, but one as Black as default and the other as Color. I suppose this also will cause issues for the Print Pool functionality to work well.
This is the first time I've used Print Pools so I hope someone can confirm/answer my questions.
Thank you in advance!
Tony

Yes this is how printer pooling works. Other posts in this forum discuss the issue.
Add a port that is will enumerate first in an alphanumeric sort. Then stop and start the print spooler service. This port will become the default port because it appears first in the sort order. From your previous statement I am assuming
nr 2 was created after nr 1 but the spooler has not been restarted so the new sort order is not yet active.
The print spooler service has no clue about copying at the device. Most of these devices have a hard driver and the data is released to the device. Copying will never prevent dropping a print job to the device unless the hard drive
is out of disk space. The device will generally not start printing the job until the person standing at the glass has completed their task but this is unrelated to the print spooler on the server.
You can setup multiple printers that are pooled using the same ports. The first port in the enumerated list will be used by both shares when the port is not in use.

Fix For Slow Printing To IPP Printer Pool

Here's a fix that might help someone out there:
I have a printer pool with two HP Laserjet printers that's shared via IPP on an Xserve running Mac OS X Server 10.5.
One of the printers is offline with a fuser error, so as expected, the server is sending all jobs to the other printer; however even small jobs are now taking an extra 1-2 minutes to get to that printer. Before one of the printers went offline, small jobs would print almost instantaneously.
Since printing speed was normal for other, non-pooled printers shared by the server, I figured the delay was probably related to the server taking too long to decide that the offline printer was actually offline.
I figured that the fastest way for the server to determine that a pooled printer is busy is when it has a job in its queue waiting to print. So, I logged into the server and sent a job directly to the offline printer's queue; the job will just sit there and won't print, but the server will think the printer is busy.
That eliminated the delay. It's annoying that the delay is there at all, since the whole point of the printer pool is too have redundancy if one printer runs out of paper or malfunctions. If anyone has any ideas on a more concrete way to eliminate this delay, please share them.

Hi,
Do the programs freeze for about 2 minutes each time when attempting to print something?
Do we use spooling? If not, we can enable the setting
Spool print documents so program finishes printing faster and its sub-setting
Start printing immediately to see if it helps.
Regarding this setting, the following article can be referred to for more information.

Printer Pool load balancing problem.

We seem to be having a problem with printer load balancing working correctly. I have several computer labs. Each lab has at least 2 printers of the same type. As a result I pool the printers for each lab. We are still running ZCM10.3.4. Most of the clients are running iprint 5.82. With Zenworks 7 and 6.5 load balancing on these printers worked very well and page counts stayed very close on each printer. Now that we are at ZCM10 and have been for about 3 years now we continually see that one printer gets the majority of jobs. Most of the computers are imaged but printers are installed after imaging. Even if we alternate the default printer on the computer print jobs still mostly come out the same printer. All printers except 3 are HP and in our case they are all new HP M602's with a couple older HP4015DN's thrown in when the new HP M602's would print garbage across the wan and the 4015's would print correctly but that is another topic.
Am I misunderstanding how load balancing is supposed to work? Isn't load balancing supposed to be one of the features of printer pooling in addition to sending jobs to the printer that is not busy at the time the job is sent? How is load balancing set up?
Thank you.

are you using any front end web server or hardware load balancer ? verify your load balancing if it's happening or not properly between your clustered managed servers.

Printer Pool & Printer Status problem

Hello,
I have a Printer Pool setup with 3 HP LaserJet 1320n's. The pool is working correctly when all 3 printers are online and operational. The first print job goes to #1, second to #2, third to #3, then back to #1, and so on.
When I turn off one of the printers - the printer pool still sends print jobs to that printer and basically waits until it gets turned back on.
From my understanding -- the printer pool should recognizing that it can not access #2 and send the print jobs on to #1 or #3.
I have tried to add the printers on the server via LDP & HP Socket - with both the correct HP drivers and Generic Postscript -- all with the same result.
I am running Mac OS X Server 10.4.11.
Thanks
Brad

I've been trying to get this to work and have a little more information to add to the problem...
* I can add a printer pool to the managed printer list from an OS 10.4 client, but not from the OS 10.4 server. In other words, add the pool to the client via Printer Setup Utility, then use Workgroup Manager on the same client to add the printer pool to the managed printer list; however, the printer pool will not appear in the managed client's printer list.
* I've tried sharing the printer pool via both LPR and IPP with no success.

Printer pool problems

Hi I was wondering if I can get some feed back on a issue I'm having. I'm running an IMac OS X 10.9.5
and I have two DNP DS40 Printers and I would like to print at the same time using printer pool.
After sending first job to printer A I send a second job to printer B the system will tell me that job A is printing and it does
But job B is waiting for available printer ( which is there idle) when job A finishes Job B will start on the printer that Job A just finished.
Basically All jobs just go to one printer even though both printers are good to go in printer pool.
Can anyone tell me how to correct this?
Thank you
Joe..

No..I setup the printers and they want to be one. Tried them as one as well, but still only send to the same printer. Only turning off that printer will allow the other to be used. I setup a Printer Pool and still only uses one. Haven't tried on Mavericks or prior...does it print to both on that OS X? The OS seems to not allow for more than two printers of the same make and model. Software like the PC printer hot folder is needed on the mac.
Color is perfect. Speed seems to be a little slower than expected, but that is probably from the os. You have to call DNP support for the Yosemite Beta driver.
I am confident it will get fixed, but how long will it take.

Printer Pool does not appear in Available Printer list

I run a school lab with 35 iMacs in it. We have 2 network printers. I am trying to set up a print queue on our XServe to pool the printers so that jobs will go to whichever one is free/not out of paper/etc. I have successfully set up queues for the individual printers and I have created a printer pool, which I set as the default queue.
The problem is that when I look in the students' available printer list, all I see are the queues for the individual printers and not the pool. How do I make the pool appear so that I can set it as the default printer for the students?
Thanks in advance.

Apparently, that is how it is designed.

Printer pool won't work

I've set up two Canon ip6600D printers into a printer pool. I can get each printer to work individually, but I can't get them to work as a pool. If I send 4 print jobs to the printer pool all four get printed on the first printer rather than two on each. Anyone hae any suggestions.

Anyone fix this? I have the same issue and the Security preferences don't seem to be the issue. I have two computers on Leopard. It worked when they were in Tiger, though.

Different print mode behavior between 1.5 and 1.6.

We recently upgraded to 1.6. There seems to be some behavior that is working differently now(no other changes made).
Here is the situation:
I have a tabular report of projects with a link column that allows the user to go to a page of each project's detail. The column link has a passed in P50_PROJECT_ID that the detail select uses. The detail page has some general project detail information like name, project manager and this is displayed as items in an HTML region. The items are populated by a process that fires before header and selects the information INTO the item variable(:P50_PROJECT_NAME, :P50_PROJECT_START_DATE...etc). There are also two tabular reports based on SQL queries to display milestones and issues for the project. These are based on queries that have the WHERE clause using the incoming :P50_PROJECT_ID.
On the detail page, and all other pages in the app, I have a Print navigation bar entry. This navigation entry target type is "Page in this application" and Page is &APP_PAGE_ID. Printer Friendly is checked on.
The app was built with 1.5 and when the user went to the project detail page and clicked the Print link, it worked fine and showed all the data. After we converted the APP to 1.6, after the user selects the PRINT nav item, the page is re-invoked and the detail data shows up fine but the tabular reports show with NO DATA.
It looks like I can fix this by changing the Print navigation bar item to SET P50_PROJECT_ID with &P50_PROJECT_ID and it works fine but I'm not sure that's the way to do it since the PRINT nav item is used on many pages(that may not use the P50_PROJECT_ID) and I'd like to know if there is a reason it's not working now and worked before?
Any input is appreciated!
Thanks,
Paul

Hi,
I haven't used Java 6 yet, so I don't know about the performance improvements, but I don't find it strange.
Calculations using floating points can give different results in different VM versions and on different platforms. You should declare the class to use strictfp if you want to get the same result on all implementations (that is of course slower)

Printer pool quit working

Running print services and our email from a G5 Xserve on 10.3.9. I pooled 2 printers through the printer setup utility but the pool has taken a hiatus. I can print directly to the pooled printers through the server, but the print jobs go into never-never land when attempting to print to the pool. Strangely enough, the pool works for Windows, but not Macs?!? Any help you might offer will be appreciated. I did rebuild the queues and the pool to no avail.

Persistent Chat Pool Behavior for Multiple Sites

We plan to have 4 Lync 2013 Standard Persistent Chat servers, 1 in each site. They will be part of the same Persistent Chat pool.
Is there a way I can force Lync clients within a site to connect to its local persistent chat sever? I am trying to accomplish this without a hardware load balancer.
Not sure if you need to know but our front end pool setup consists of:
1 Lync 2013 Standard server (Production site A)
1 Lync 2013 Standard server (DR site A)
1 Lync 2013 Standard server (Production site B)
1 Lync 2013 Stanrdard server (DR site B)
We are using pool pairing for DR.
Thanks.

These are typically DNS load balanced. If you want to force it, you'll have to have your DNS servers reply with the most local address. This isn't an easy task with Windows DNS. I can think of ways to hack it (keep the pool name out of
an AD replicated zone and use pinpoint DNS that would be manually updated for this).
That being said, I wouldn't kill myself over it. The amount of traffic used for persistent chat is very low as it's really just text chat being sent back and forth. Also, the real data is in the SQL server DB, not the PC role, so unless
you're splitting that across four sites, I'd just leave it.

Group Policy Preferences Printer Delete Behavior

I just had a maddening time trying to get Group Policy Preferences to delete printers. I'm sharing what I found out so that you might have a better experience.
1. Even though the field is grayed out, if you have something in the "Local Name" field, the printer will only be deleted if the name matches what you have here.
2. If the "Local Name" field is empty, one printer with a matching IP address will be deleted. If there are multiple printers with the same IP address, the policy will delete them one by one each time a refresh occurs unless you've got the "Apply
Once" option active.
The client I tested with was Windows 7 with version 6.1.7601.22249 of group policy preferences installed.

After more testing, it turns out that all of my observations were correct:
1. Even though the field is grayed out, if you have something in the "Local Name" field, the printer will only be deleted if the name matches what you have here.
2. If the "Local Name" field is empty, one printer with a matching IP address will be deleted. If there are multiple printers with the same IP address, the policy will delete them one by one each time a refresh occurs unless you've got the "Apply Once"
option active.
3. If the "Local Name" field is empty, a warning '0x80070709 The printer name is invalid.' will be logged in the Application log. If a printer exists, it will still be deleted. If the "Apply once and do not reapply" option is checked, the
warning will still be logged every time group policy refreshes. This warning can be prevented by configuring "Configure Printers preference logging and tracing" to only log errors, but then you potentially miss out on warnings about actual problems.

Ip pools behavior, simultaneously login same username

I notice that, the ip-pool system does not function properly when a username is used twice @ the same moment. the 2nd user gets the same ip address assigned & i see a : nas port re-used: message in the log. ACS 3.0 windows.
Can i get this to work ? how ? upgrade necessary ?

Sorry, my apologies, I thought this change would be automatic but then wondered how on earth ACS would figure out different session if they have the same port number.
Researched the bug a bit more and what they did in 3.2 was add another option under each NAS. Go under the Netowrk Config section and click on the specific NAS, scroll down and you'll see a checkbox for "Replace RADIUS Port info with Username from this AAA Client". Check this, and ACS will then use the username rather than the port info for this NAS to define different sessions.
Having said that though, I don't think this is going to work for you because this relies on different usernames being used, which in your case it isn't. The bug seems to have been created (and fixed) for NAS's that don't include a NAS port in their requests at all, and so ACS can now use the username as the definer for each session. The caveat to this bug though is that usernames have to be unique, if the same user logs in they'll get assigned the same IP address out of the pool.
The crux of all this is that if you're using the same username on the same NAS, and that NAS is using the same port number, how is ACS supposed to know this is for different sessions?

Is it possible to print one document to two printers?

I need to print one document to two printers at the same time.
Can I accomplish this with printer pools in OSX Server? I've found several 3rd party vendors for Windows, but nothing for the Mac.
Any help would be great!
Thanks!
Josh

Thanks Alec!
Is there a way to get the print pool to print to both printers at the same time? With the pool it just switches the jobs between the two right?
I actually need to click Print once, and have it print on both printers.
Thanks for your help!

Can't connect to Network Printer

I just bought a laptop with Vista. I have wireless router connected to a wired router. My two desktops are conneted to the wired router and the laptop is wireless to the wireless router.
My printer does not have a wireless card, so I have it plugged to one desktop, and I have the other desktop using it as a network printer.
I can't seem to get the wireless to see the printer. I have enabled file & print sharing on all computers, and the print spooler service is started on all computers. When I do "Add a printer" it doesn't see the printer. I tried doing "Add a network printer" and entering the name as \\computername\printername (where computername is the computer the printer is attached to), but I alternately get these two errors:
"Windows cannot connect to the printer. The server print spooler service is not running. Please restart the spooler on the server or restart the server machine" or
"Windows cannot connect to the printer. Makes ure that you have typed the name correctly, and that the printer is connected to network."
I have not been able to see the desktop computer at all in the network options, but I do see the wired router listed, but no computers connected to the router.
Can anyone help with this? I am at my wit's end. Dan

"Windows cannot connect to the printer. The server print spooler service is not running. Please restart the spooler on the server or restart the server machine" or
see the tail end of my thread here, it sounds a LOT like your problems and my own are similar:

Hello,
http://support.microsoft.com/default.aspx?scid=kb;en-US;2388142
Might be the right hotfix!
I will be trying this hotfix this week. I have this problem SO bad right now. The only slight difference is that my print server is running Microsoft Storage Server
2003, and all my clients are now windows 7. The problem hits users at seemingly random times, random 5% of the company per day, and all printer pools...it made no sense at all!
I'll keep you posted as to whether the asyncronous RPC reg key helps, or if your hotfix does.
There is also something i found that works (for 48 hours straight anyways):
On vista/7 client, go to Devices and Printers and click Add Printer
Then choose Local Printer. I know your printer is shared on a print server, just stick with me here!!
Choose Create New Port and select Local Port...
When it asks you for a port name, type in the UNC ADDRESS of the printer (ie \\printserver1\HPLaser5000n).
When it asks you for a driver, point it to the right location where you downloaded a clean set of drivers matching your client OS and printer. Or press the Windows Update button.
finish adding the printer. You will notice the name of the printer doesn't have a "...on [printserver1"
anymore, BUT it will still print!!
I have done this for 4 printer pools and for the last 2 days the 1 user i set it up for has had no printing problems. May be total coincidence, but at this point i was willing to try anything. I'm not sure if this constitutes fooling windows 7 into setting
up a remote printer as a local printer, and i'm also doubting this will be deployable via GPO or script...but still, i hope it helps.

Remote Desktop doesn't work with local printer

I am having trouble using a locally networked printer when I use Remote Desktop to connect to a Vista machine. Under the local resources tab for RD, I have checked printers. The only thing I can figure is that my printer is networked locally, not connected directly to my machine. Every time I try to print during my remote desktop session, I can't access my locally networked printer.
I installed the printer drivers on the remote computer and when I try to locate the printer, I get the following error: "Windows cannot connect to the printer. Server print spooler service is not running..." but the spooler service IS runing.
I also found a post elsewhere that discussed setting 'share permissions' and 'network permissons' to resovle the spooler error. Still no go.
I tried to plug in my printer to a local USB port this morning. Still would not work. I keep getting the same spooling error. The drivers are not corrupt, as others have indicated may be the cause. They work fine on my system locally with 7.
Any advice would be greatly appreciated. I've spent a few hours on this one and am at a loss at this point.
Please help. I really need to print locally.

My problem was that the Vista remote system never saw local port that my printer was using for some reason and it never accepted the path noted above (\\servername\printer)...always came back with an error that it was an invalid path. This was with it both networked and plugged in via USB port.
I finally figued it out after four days and many hours on the phone with Microsoft. Microsoft support claimed that it was related to my router settings, but I didn't believe it since the remote computer saw my iPhone just fine when it was connected locally. After simply playing around, here's what I found...it was actually quite basic!
On the remote system, when you try to add a 'local' printer, there's a drop down menu with a list of local ports that your remote system sees. Some of those will be on the remote system, but others will be on your local system. Make a note of the ones that are seen on your local system. In my case, LPT1 was not visible, but COM3 was.
Next, on your local system, in the settings for your functioning printer (Printer Properties, Ports Tab), there's a tick box that says "Enable Printer Pooling." Once you check that box, you can select multiple ports on your local machine. Here, you need to tick the box that your remote system is seeing (in my case, it's COM3), but make sure that your exisitng port remains checked as well (in my case, an IP port for my wireless router). Basically what you're doing is on your local system, you are pooling your exising printer setup with a port that can be seen by your remote system.
Then, on the remote system, install the printer drivers but don't select a port. Then go into Printers and add a printer. Select 'local' setup for that and when asked for the port, use the port you checked in the previous step on your local system (in my case, I selected COM3 on my local system). Select your printer from the list. It will ask if you want to use the exisiting drivers...say yes. Then print a test page to be sure that it works. Worked fine for me.
I simply can't believe how obvsious that solution was! If the remote system can't see the port you currently use, pool your printer setup with a port that it can see!
