Network printer

[Antonio M]

I have a mixed network with Windows XP, F8 and F9 (rawhide)
I am sharing an HP Laserprinter (that is attached to the XP machine)
and I can print from F8 computer, but I can't from F9.
Setup is similar. Printer is detected from config-system-printer on
both F8 and F9 but when I print a test page from F9 nothing happens.
I gave a look to log files for cups but I didn't see anything strange!!!
Where shall I start to look from scratch????
Cups is v.1.3.6 on both Fedora machines.
