Anyone have any idea what could be the issue? printer driver correct, win 7 pro (and also xp pro sp3) PCs stopped printing to Network printers after this morning updates. Others (PC withot updates) have no issues at all. Printed doc goes to que and just stays there. Clearing the que and restart still no help.

View the update history and remove today's updates one at a time until you get the network printer working. Alternatively, you could restore to a point prior to the updates and then selectively install the updates until you find the culprit. Once you know which update caused the problem, you can determine the cause. Check Hotfix KB2028551: http://support.microsoft.com/?kbid=2028551 Do you have office 2007 or 2010 installed? or remove the printer and reinstall and leave the hotfix. See which will work for you?
