That appears to be it.  I opened the task manager and changed the compatibility 
setting on all three running Epson driver processes from Vista to XP Service 
Pack 2. [This is done by right-clicking on the process, selecting "Properties" 
and then the Compatibility tab.] Printing now works.  Thanks for sharing your 
suspicion about the underlying cause of the problem.
