Printer goes offline until reboot (network printers)

On a windows 7 professional machine, all network printers show as "offline". If the machine is rebooted they go onine, work fine and everything in the queue is sent to the printer properly.

After a while, the printers will show "offline" again.

Does anyone know what could cause this or how to troubleshoot?

First of all, ensure that you have the latest drivers for your printers.  After that, it would be a good idea to manually clear your print queue:

1. Open a command prompt with full admin privileges:  click on the Start button, enter cmd in the Search field, right-click on the command prompt icon and select Run as administrator

2. Within the command prompt enter net stop spooler

3. Use Windows Explorer to navigate to %systemdrive%\Windows\System32\spool\printers\ and delete all of the files within that folder

4. Return to your elevated command prompt and enter net start spooler

Sounds like the Print Spooler is crashing.  Next time they go offline, check to see if the Print Spooler Service is running.  Administrative Tools -> Services or run Services.msc.  If it's offline, check the event logs for errors.  You can then just restart the Service and they should come online again.  I had a problem where a HP Driver was crashing the Print Spooler.  Had to replace it with a different driver.

Ok, I will look into this. One thing I should note; no errors are popping up on the screen. No spooler unavailable etc.
Did you look into the problem further?  Are you still having issues?

The primary person using this machine is on vacation. I'll be able to check it out next week. Thanks.
