Can't open printer connection

I now have the following setup:
iMac G5 (LAN port) <--> Belkin 5-Port Network Switch via Ethernet
HP 7210 (LAN port) <--> Belkin 5-Port Network Switch via Ethernet
Airport Extreme Base Station (LAN port) <--> Belkin 5-Port Network Switch via Ethernet
Cable modem <--> Airport Extreme Base Station (WAN port)
The network seems to be working fine as far as internet access goes. On the Airport Admin Utility, I have the Distribute IP addresses box checked.
When I try to print, the HP Officejet 7200 series dialog box opens and says "Opening printer connection" but nothing ever happens.
What do I do?

HI Sean:
I had the same problem too!!! I was getting frustrated because I was trying to
get my hp photosmart 7260 and my hp deskjet 3740 to print wirelessly. The solution I found by accident. What happened is that my network went down so I decided to unplug my cable modem connection from the Lan Connection on the Airport Extreme Router and plug it in the Wan connection and presto my printers were printing wirelessly. When that happened I literaly just wanted to cry in happiness.
Hope this works for you. Please let me know what happens. My email is [email protected] if you want to contact me.

FTP exception: Can't open passive connection: Permission Denied

I have a File sender adapter, with FTP as transport protocol.
The adapter polls a directory each 60 seconds.
All works perfectly but <b>sometimes</b> I get the following error :
Channel CC_GBL_FlatFileSender: Error connecting to ftp server ...: com.sap.aii.adapter.file.ftp.FTPEx: 425 Can't open passive connection: Permission denied.
And 60 seconds after, no more error.
Any idee of why I get this error occasionally ?
In the sender file adapte, data connection is set to Passive. Do I have to set it to Active ?
Thanks in advance,
Laurence

Hi
Data Connection
- Active
In active mode, the server establishes a data connection from its data port, port 20, to an end point chosen by the client.
- Passive
In passive mode, the client establishes a data connection to the port required by the server.
The default setting is a passive data connection. Only change this setting if you have a specific reason. This is what is recommended by SAP.
It is possible that Passive FTP mode may terminate session.
In this mode the server "listen" on a data port (which is not its default data port) and to wait for a connection rather than initiate one upon receipt of a transfer command. The response to this command includes the host and port address this server is listening on.
In the FTP protocol two ports are normally used, 20 and 21.
Port 21 is the control channel in which requests such as PUT, GET, and PWD are sent to the server.
Port 20 is the data channel in which actual files, folders and directory
listings are sent.
Normally, when you connect to an FTP site, the site establishes the data
connection to your PC (the client) on Port 20. However, if the site allows
passive transfers, you can have your PC establish the data connection. It is
recommended that you use passive mode for most transfers.

IMac can't see printer connected to Windows 7 PC via USB

Hi all,
I have a mixed PC/Mac (Snow Leopard & Leopard) network and a Canon PIXMA MP780 printer connected to a PC running Windows 7. Last week, when this printer had XP on it, I could print. Since "upgrading" to Windows 7, the Macs can no longer see the PCs on the network. Clearly this is a Windows issue but I opened a support ticket with Microsoft and was told it is a Mac issue. (SOP for Microsoft) I'm hoping one of you has figured out how to get your Windows 7 PCs and Macs talking to each other. I can't manually add the printer to the Macs (can't even see the PCs) so we are dragging a USB around the office until we get it working. Fun all around.
Thanks, Denise

My best recommendation for the last 4 or 5 years has to been to only buy network (ethernet) printers. There are many available for under $100. Why put yourself and your office through constant changes caused by upgrading or changing computers? If the printer manufacturer makes drivers for your printer for the OS you want to use, then you're done.
This way, all of your OS's work with the printer in their own way, without having to make considerations for bugs or new services, or changes in the way the OS works on a particular computer. Also, if a computer dies, it doesn't take down your shared printer with it. The other computers don't have to even be turned on for you to print.

Opening Printer Connection

I have OS 10.10 Yosemite installed. Prior to this, my printer has worked flawlessly for a few years. I have the latest HP drivers installed (now provided by Apple update).
Now, after the first print job, the print connection seems to fail. This is through USB. I've repaired permissions, removed and reinstalled the printer, reset the printing system, restarted the printer, and restarted the computer. I have to remove and re-add the printer each time for each print job. Yuck.
Sometimes after I reboot the computer, it will print a number of jobs in a row. Then the problem will start up again.
Any thoughts?

Unfortunately, that has not solved the problem. It's connected to the iMac directly, and I've switched the cables. However, it wouldn't call this a hardware problem or one that is particularly intermittent. Yes, sometimes if I reboot and reinstall, it can take a little while for the problem to recur, but it consistently does so and it is always the same. The print queue shows show the following :
Notice how it states that it's opening the printer connection and displays the previous job that printed as "100% complete". Then it hangs at this specific point every single time. Once again, this is a new problem that surfaced with Yosemite after a few years of rock solid functionality. I believe this is not a hardware issue; it appears to be software.

Can't open print & fax preferences, can't print

I know I've read about this problem before, but I can't seem to find the thread. I'm a total novice when it comes to terminal, but I don't even know where to start. Whenever I try to print, or even open print & fax, I just get the spinning wheel. I'm using Leopard on a 17" MBP, and I'm set up on a network with several printers (I can't even open the individual printers...everything related to printers or printing just freezes!!)
Any help is much appreciated!

I think I have bigger problems here...
I think you may be right.
Have you installed anything recently?
Open up Console.app and see if there are any messages that repeat regarding the crashes.
How much free space do you have on the disk?
You can get into the CUPS web config through http://localhost:631
I couldn't find anything like "Reset Printing System," but you can view the error logs (which you can do from Console.app), and edit the Configuration file. There is a button to use the Default configuration, but I don't know what that will accomplish. Might be the last ditch effort before reinstall.
EDIT: From About the Reset Printing System feature:
What does Reset Printing System do?
Deletes all printer queues and jobs.
Resets all printer settings to their default by deleting configuration files.
Performs a permissions check on the /tmp directory.
1) Can do that from CUPS interface
2) Noted above
3) They should be rwxr-xr-x root:admin

Can we open multiple connections to APNS Feedback Server

Hi,
Is it recommended/allowed to open multiple connections to APNS feedback server to poll the bad tokens?
The idea is to run a timer task (every hour) on a n application server which will poll the apns feedback server to retrieve the bad tokens and then close the connection every one hour from N app srevers.
If it is allowed, can multiple parallel connection get the same bad device tokens connected/read at same time?

You are literally correct in that IP addresses can be spoofed.
But the same argument can be made about any single, known, form of security.
If I know it is the fingerprint from your left index finger that is required ... I've no doubt I can break in if I want to badly enough. Sorry about the finger.
Security comes from layering multiple, unknown, security measures.
Mix invited nodes with a known userid
SELECT sys_context('USERENV', 'OS_USER') FROM dual;
and the hacker has to know both a valid IP address and who is supposed to be there.
Now on top of that add the operating system information:
SELECT sys_context('USERENV', 'TERMINAL') FROM dual;
and it becomes a bit more difficult.
Layer on a few more and it becomes exceedingly unlikely anyone will get in that doesn't belong there.

Can't open printer web access page.

After installing Firefox v.17, I can't open my printer's web access page.

Can't open TCP connection when two network adapter are enabled

Hi all,
I've an applicaiton that connect using "TCP Open Connection". The applicaiton is running on a computer have two network adapters configured to be on two different network.
When I start the application, if both network adapters are enabled, connection is not created (timeout). When I disable the network adapter which is not configured for the network I need, connection is succesfull.
- How can I choose which adapter to use to open the connection, as LabView seems enable to select the good one.
- Or I can I disable a network adapter (just for the connection time)
I'm using LabView 8.5 Full on Windows XP.
Thanks for your help

This is generally a routing issue. The OS will route connections to your primary network if it is not a direct route. For example, one network is 10.3.4.x (primary network) and the other is 192.168.1.x.with a subnet of 255.255.255.0. Now, let's say you want to reach a device with an 192.168.2.x address. The OS will try to route this through the primary network but is has no route to reach the 192.168.2.x subnet. Therefore your connection fails. You can add a permanent route to your computer to force specific address ranges to specific NICs. Use the ROUTE ADD command which is part of the OS. If you are trying to reach the computer using a name instead of the IP address the issue is basically the same but a but more challenging to resolve. The OS will do th elookup on your defined DNS servers. They generally do not have knowledge of local private networks and therefore can't resolve the name. In this case you need to create a more involved network infrastructure to update the name server. Probably not something that is feasible to do.

Opening Printer Connection Hanging

All of the sudden I cannot print.
Printer is connected directly to Time Capsule and then wireless to my MBP.
It was working fine yesterday.
So far I have deleted and added the printer.
Before I go any further does anyone have suggestions?
Thank you
Michael

I've deleted the printer, renamed it, added it again. But no luck.
My MPB can see the printer it just seems to hang when trying to connect to it.
It prints fine from the PC which is hardwire networked.
I'm going to try trouble shooting the printer now.
On the PC I restarted the Printer Spooler service.
Then I simply unplugged the Printer for 5 minutes.
On the MBP I again deleted and reinstalled the printer which it found no problem. It may have updated the drivers at the same time.
I tried printing and noticed that it defaulted to "Last printer Used" I changed this to the recently added printer and it worked.
Not sure which of these made the difference.

Can't make printer connection

Lost my printer connection about 10/25. Was able to get going by zapping pram and doing a disk repair. However the problem re appeared in 24 hrs. Now I find it all started with MOZY - which I have. They gave me a "fix" which included an uninstall of the present MOZY. Problem is I can't uninstall it because it won't accept my password ( administrative) - so I changed the password and I still can't get Mozy uninstalled. Believe me ,if I ever do get it uninstalled, I'll be very hesitant to reinstall Mozy - I'll find another one. So can you suggest a way to do an uninstall ?? Thanks - you folks are always a big help -- Monty Small

Monty, as a workaround I understand if you Repair Permissions with Disk Utility you'll be able to Print until the next time Mozy tries to Backup, can you disable Mozy's auto backup btw?
On removeing it, Could be many things, we should start with this...
"Try Disk Utility
1. Insert the Mac OS X Tiger Install disc that came with your computer, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
*Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*
3. Click the First Aid tab.
4. Select your Mac OS X volume.
5. Click Repair. Disk Utility checks and repairs the disk."
http://docs.info.apple.com/article.html?artnum=106214
Then try a Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.
(Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.)

Can't open print settings with CS5 and Epson R1900

In Photoshop CS5, go to File > Print. In the Print dialogue window, click on Print Settings... and no response. The blue Print button in the lower right corner flashes when I click, but nothing else happens.
I've tried running Photoshop in 32-bit mode as well. Doesn't behave differently.
Running on a Mac Pro 2.26 GHz (most current generation).
12 GB RAM
OS 10.6.4
Printer is connected to Airport Extreme USB (most current generation).
Can successfully print with CS4; seems to be a new issue with CS5.
Hope I've included enough info to troubleshoot this problem.
Thanks for any help!
Brian,.

I've been trying to trouble shoot this problem since the beginning of September. I wasn't sure if it was a snow leopard issue, a Driver issue, or a CS5 issue. I guess it's CS5. I recently discovered the work around of asking Photoshop to manage the colors, opening the print settings, saving, then returning to printer managing colors but this just doesn't cut it in our graphics lab. We need the settings to be as straight forward as possible for our students.
Also, unrelated sort of, Photoshop remembers the settings from the previous print job. Which again doesn't work well in a lab/public environment. So if jimmy printed 20 copies of a file and set it to print colors as gray; Susie, the next in line, would have the same print settings for her file. This seems to only happen with photoshop. Not Preview, not safari, nor any other program.
We're seriously considering moving back to CS4.
...at least that had contact sheets.

Can I access printer connected to windows PC on my airport network

I have an airport extreme network with 3 MACs and 1 Dell laptop (yes I had to get a used Dell to run Mural Creator and TileCreator). Three printers (a dye sublimation printer, a Canon i9900, and an HP laserjet 3380) are connected to my airport extreme base station using a USB hub. I can print to any of them from all computers. The Dell is in my studio and I connected a HP Photosmart printer to it. How do I print to it from the MACs?

Hi Stephen!
You're not providing us much information about your problem. Is the printer still connected to the Windows computer or do you have it connected to the Mac? Or are you trying to print across a network from the Mac to the Windows computer? What model printer? What have you tried? What doesn't work?
Do this...
First, while in the Finder on your Mac go to the Help menu and search for an answer there.
Next, if you don't find an answer come back here to this forum and use the Search feature in the upper right corner of each page to search the older posts. Mac and Windows printing questions are plentiful here and just about every answer has probably been given.
Finally, if you get stuck post a new question that specifically details how your computers are set up with your printer, what you've tried and what you're needing to know or have answered.
Since you're already here and looking for information I'll also point you to this excellent information posted by iFelix, a regular visitor to this forum <http://www.ifelix.co.uk/tech/index.html>.
Hope this helps and good luck! bill

It's what it says really.
Try opening up a Word document. Then go File > Print. BUT instead of selecting your printer at home, you should see a printer called 'Print to Go'.
Select it and Print. The Word document should then be 'printed' to your PlayBook.

Can't add printer connected to other mac on network

I've got a new Epson Photo Stylus R380 connected via usb to my desktop G4. That G4 is hard wired to my airport express network. I've got the printer drivers, utilities installed on the desktop G4 and the printer works just fine. Now I'd like to print from my powerbook to the Epson but I don't see it when I try to add it. I do see the HP printer that is plugged directly into the airport express. I was able to print to my previous epson color printer that was plugged into my desktop G4 so I don't know what I am missing. Please help. Do I need appletalk on or off? What other setting should I check?
thanks.

The description of your problem sounds like you have had no other printers hanging off a usb port of this desktop G4 for awhile. Is it possible that you disabled printer sharing on your desktop G4 at some point in time in the past, a la post-Epson-color-printer? Doublecheck your desktop G4's system preferences > sharing > services and make sure that printer sharing is still checked on.
If that was indeed the problem, then on the powerbook, when you ⌘p, in the subsequent print dialog window, one of those pulldown menus should have something about "shared printers" that you can add this usb printer hanging off your G4 desktop.
