There are a variety of things we'd need to know:
Operating system version
Rip Yes/NO
Printing from Photoshop yes/no.
QImage yes/no
etc.
But assuming that you are using windows xp:
1) check that you don't have a message lurking somewhere.
2) check on the print queue itself to make sure there isn't a document spooling already -- windows is always slow....
3) go to settings, printers, properties, advanced, and select spool print documents. You may have to restart windows and/or end any current print jobs.
Hope one of the above help....
