Printing with Win98 causing problem

My PC is running Win98 and networked to NT Server 4.0 . Everytime I print from any application, windows or not, I get an illegal operation. The error reads
Example: “Excel caused an invalid Page Fault in ISM.DLL” or if not ISM.DLL it is in Kernell32.DLL. Then the Error window stays on the desktop. If I “X” it, it just returns so I have to reboot the PC everytime. Any help on this matter will be greatly appreciated

Regards
