Windows – Network Printers Offline (but not really)

networkingprintingwindowswindows-vista

I have two Ricoh printers/copiers setup for IP printing in the office.
Before this week there were no problems printing to them.
Now a handful of them (All running Vista, not sure if it is every Vista computer or not, It seems like I would hear more from users if that was the case), see both printers as being offline. All the PC's running XP have no problems printing. When this first occurred a reboot was able to get the printer to appear online, but that is no longer the case. (and at the time I thought only one computer was having the issue) I have removed the printers, reinstalled the latest drivers and there is no change on the Vista machines. I am currently using the same version of a RPCS driver on both VISTA and XP. As a work around I could setup the printers on a 2003 Server, but I don't see why IP printing should just stop working out of the blue like this. The printer can be reached by IP from all computers and the web interface is accessible and reports no errors.
Does anyone have any ideas?

If all else fails, you can disable SNMP monitoring in the printer's TCP port properties. You won't be notified when the printer becomes ACTUALLY offline, but you won't get false positives anymore.
