Remote desktop printing over VPN to local TCP/IP printer hangs until computer rebooted or another job is sent

We have used this scenario with XP and had no problems.  Now the client has replaced both computers with Windows 7 SP1, latest updates installed.

The printer is a Konica Minolta Magicolor 1690MF over standard TCP/IP at the users home office.

The user will remote into their office PC over a SSL VPN (as previously with XP).  The printer drivers were installed onto the Office PC in order for the printer to show in the list.

A test print can be sent initially from the remote computer with little delay (under 1 minute for a small job).

Any subsequent prints from the remote computer will pop into the local print queue (printing) and then disappear but the print job will not come out.  Restarting the local or remote spooler does not make any changes.

Rebooting the local computer will cause the prints to come out.

Sending a local print job will cause a previous print to come out (say we sent three remote print jobs that never came out, the oldest will then print) but the local print will not come out.  We can then keep sending a local print job to get the older jobs out.  The only way it seems to get all of the jobs to print is by rebooting.

Other things that have been tried: set "print directly to printer"
Turned off SNMP
Contacted Konica Tech support which had us change sleep time.

Has anyone else seen this?

Unfortunately we don't have any other printers at the client's home office to try as they only have two of the same KM 1690MF units.

They have another new Win 7 desktop that has the same problem from this location.

Shared printer offline after reboot fix…
Posted by admin on March 24, 2012

When you add a shared printer in Windows 7 that needs to have credentials to be able to connect, it might only work the one time immediately after adding it. After a reboot, it will be offline and you can only get it to come back online by removing and adding the printer again. To remedy this, you need to store the credentials for the print server onto the client machine. Simply checking the ‘Remember My Password’ box is not enough.

Go to Start -> Control Panel -> User Accounts and Family Safety (if in Category View) -> Credential Manager -> Add A Windows Credential

Enter the path to the print server, user name and password (of an account on the print server) then click ‘OK’. Now add the shared printer as you normally would and all should be good!

This supposedly applies to Windows XP and above but, I have only encountered this “feature” on Windows 7.

Note: If the client machine and print server happen to use the same credentials (as in a corporate network), everything will work as expected without problems. Only when the client machine has different credentials than the print server will Windows prompt you for your credentials because it cannot log on to the print server. Also, Windows 7 will sometimes give error 0x000052e instead of prompting for the credentials.

Thanks for the input but this does not seem to be the same issue.  This always prints after a reboot but stops working after a short while and the printer does not show as "offline".

Try this go into the printer properties/ ports /configure port and uncheck the SNMP Status Enabled.  See if that doesn't fix issue.

Hi Tmoore1962, that was in my list of items already tried which did not fix it.

Thanks,

Best setting for spooling over a vpn is "start printing after the last page has spooled"

disable bidirectional communication in the port properties.
Try changing from raw to LPR.

Turned out to be an issue with this printer utilizing a GDI (host based driver).  I've never liked those drivers but with XP it never caused an issue for them.  Replaced the printers with two PCL driver HP printers and they are running at full speed.  Thanks for the input.  Hopefully this will help someone else.
