Netware 6.5 SP2 & SP3
iPrint NDPSM 3.01

We have several different version of Xerox printers. Recently we moved to
iPrint with XP Client. Many Xerox printers (DC235, DC405, C4P etc) simply
do not print. They come with 'Error in printing' message. We tried TID
10080373 but no help. We tried PCL and Post Script drivers and that didn't
help either. We use Novell Gateway under NDPS. We have tried the printer
name as PASSTHROUGH and lp

This put us under lot of trouble from user community. Any ideas.

Is there list of printers that are not supported by iPrint environment ?
