Spool32 error

Problem: User is getting “spool32 caused an IPF in kernel32.dll” sometimes when printing from Word 2000 In WIN98SE.Once she got a “Winword caused an IPF in module unknown” when Word was not open (could have been a remnant) Printer is HPLJ2100. (There is no printer management software installed.)It locks her up and sometimes nothing will allow her to shut down except pulling the plug! Sometimes doing CTRL-ALT-DEL show Word is not responding but even after ending task she is still locked up. I have reinstalled the printer driver and done a Word repair. Don’t know if the problem could be Norton AV but have found nothing helpful on their knowledge base. Any ideas would be appreciated!
