Troubleshoot printer problems. Microsoft Mr. Fixit

I see an error message about "spooler" problems, or the printer is
printing more slowly than usual.
A print spooler is software that temporarily stores print jobs on the
computer hard disk or in memory until the printer is ready to print
them. If you've been waiting an unusually long time for a document to
print, or if you see an error message about the print spooler, spooler
subsystem, or spooler resources, you might need to change and then
restart the Print Spooler service on your computer.
To do this, we recommend that you save your work, and then restart the
computer to restart the Print Spooler service. If you don't want to
restart the computer, try these steps instead.
To change or restart the Print Spooler service: -
You must be logged on as an administrator to perform these steps.
1. Open Administrative Tools by clicking the Start button , clicking
Control Panel, clicking System and Maintenance, and then clicking
