Symptom: Computer “locked up”, SPOOLSV.EXE using 100% CPU.
Cause: Printing certain PDF files to a HP1012 printer from Windows XP and Windows 7 cause the SPOOLSV.EXE process (Print Spooler Service) to use 100% CPU. Other printer models may be affected. Please comment if you have run into this on other printers.
Stop “Print Spooler” service (may require killing spoolsv.exe from task manager or TASKKILL).
Delete all files under C:WindowsSystem32SpoolPrinters (XP/Vista/7)
Restart the “Print Spooler” service.
Make a note of the PDF file contents. Seems to be caused by scanned documents which are image files stored in a PDF. Please comment on what types of PDF’s or other print jobs cause this problem for you.
