Laserjet 1500L wont stop printing

I have a friend who has one of these printers and in some cases it keeps
printing multiple copies. I searched the Internet and found one message in
which someone said they were having the same problem and that additional
copies of the driver seemed to be being created. The post said 14 copies of
the driver and they had to shut down the printer to make it stop printing
multiple copies of the same document). I think the image that is being sent
is a complex graphic. Operating system is XP and the printer is described as
a host based printer. Does anyone have any ideas what could be going on
here, and how to resolve the issue?

Thanks, Russ
