printer spooling

[Johanne]

I have a sharp AL-1530CS attatched by a usb connection on
my main computer running Window XP.

When I send a print job from my tablet PC (running Win XP
for tablet PC) to my main computer nothing happens. It's
only when I reboot my main computer that the print jobs
print. I would like the print job to be printed as soon
or shortly after I send the print job.

Any idea?
Thanks
Johanne
