Spoolsv.exe has generated errors and will be closed by Windows. You will need to restart the program. An error log is being created. You will find that the Spooler service has stopped. Restarting it does not clear the problem. I strongly suggest delete all files in the SYSTEM32\SPOOL\PRINTERS folder. In many cases, this resolves the problem.
Microsoft reports in Q257859 that the installation of BitWare for Windows can cause the problem in W2K and XP. If you have the problem and are a BitWare user, you could uninstall it to see if it is the basis of your problems.
