Windows Printing Issues
PDF files are slow to print to certain PCL printers (Acrobat 7 on Windows)
This may also cause the printer to run out of memory and crash/stop printing.

Print Spooler (spoolsv.exe) uses 100% of CPU
Computer running slow, spoolsv.exe using most of CPU resources. Likely due to print jobs spooled which need to be cleared. If cannot delete jobs, or jobs may be queued by another user of the computer, try the following - the last step is the key, but the spooler must be stopped first (step 1, or through Services in Computer Management):
1) start => run => net stop spooler
2) in cmd.exe type in:
del /f /s /q %temp%
del /f /s /q c:\temp
del /f /s /q c:\windows\temp
del /f /s /q c:\windows\system32\spool\printers\*.*
