shared printer not printing from jobs initiated from vista pc to x

I have a printer that is hooked to an XP laptop that works just fine. I have
it to be shared on my network with my new vista desktop. The printer shows
as available when I am on the desktop. When I try to print I get no error
message but nothing happens at the printer. I tried sending two single page
jobs to it. I then clicked properities for the printer and tried to cancel
the jobs from my desktop. I got an "access denied " message. If I go to my
laptop to try and clear out the queue it does not show the jobs as waiting.
But every time I am on my laptop it shows the two jobs as waiting. Any way
to cancel them and more importantly any ideas on how to get the printer to
print them? Thanks.
