We've been having issues with the xerox PCL6 x64 driver (model specific and XGPD) for windows 7 not being able to print 2 sided via print server on win server 2003.
Here are a list of facts gathered so far regarding 2 sided printing:
-Using latest firmware and drivers
-Printing with the xerox PS driver via print server works
-IP printing with both PCL6 and PS work
-Deleting the print queue and re-adding does not work with PCL6
-PCL6 does work on other 7535 units
Any suggestions would be appreciated.
