our enviroment
Netware 6.5 SP 4a plus post patches

Clients Windows Xp Proff SP2
Iprint client 4.12

nearly every two days the user's who are attached to that printer recive a
windows error message claiming about wmrundll.exe

every time when this happens the printer state in the ndps printermanger
says, that the printer needs attention, on the printer display nothing is
shown up.

so when i now down the printer via the printermanger and start the printer
via printmanagere again everything runs smooth.

It is a realy weired problem and i don't no what to do, or where to look.

Propably someone here has an idea

best regards
