To stop the current print job using the software application
If several requests have been sent to the printer through your software, they might be waiting in a print queue (for example, in Windows Print Manager). See the software documentation for specific instructions on canceling a print request from the computer.
For Windows 98, 2000, XP, or Me, go to Start, Settings, and then Printers. Double-click the HP Color LaserJet 3550 or 3700 printer icon to open the print spooler. Select the print job you want to cancel, and then press Delete. If the print job is not cancelled, you might need to shut down and restart the computer.
