HP Printer Won't Print
 

I'm helping a friend with his HP 5400 series printer on an HP Win XP
machine. Under "Printers and Faxes", it shows 3 of the same printers.
I tried to delete the first and second one, but they remain greyed
out and "offline". The "HP 5400 Printer (copy 3)" icon shows that the
printer is ready, and it's the default printer. When I send a text
file and/or image to print, it sends it to the printer, it shows up
in the cue, but the printer just sits there. It's on, and it's
connected. When I tried to "Add a Printer", it goes through the wizard
and says the HP drivers are currently installed, yet when it comes time
to print a Test Page, it sends the page to the queue, but the printer
does not respond.

Any idea what to check first?

Thanks!
