I can only suggest:

What happens when you look inside the Printer Spooler -- double click
on Printer icon -- does it show documents queued there but not moving
on to print?

Check the spooling settings in the Printer Properties including setting
it not to spool but to print direct to printer and if set like this
works then check that Spooling is enabled.

Check in Services to see that Spooling is enabled. I've never had to
mess with this but there are messages about it here. You'd find
Services through Control Panel but I'm not in VISTA at the moment to
check exactly where.
