HP 3800 - Manual (Page 97)

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 about canceling a print request from the computer.
If a print job is waiting in a print queue (computer memory) or print spooler (Windows 98, 2000, XP, or
Me), delete the print job there.
For Windows 98 or Windows Me, click Start, click Settings, and then click Printers. For Windows 2000
and Windows XP, click Start and then click Printers. Double-click the HP Color LaserJet 3000, 3600,
or 3800 printer icon to open the print spooler. Select the print job that 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.
