problem with my printer

[vvvasso]

I have a relatively new printer HP photosmart 7960, and i have a huge
problem with it.
It want print documents or pictures that i choose, but i just get a
blank peace of paper. i thought that the printer is gone.but......
the level of ink is at its almost full,and when i start one of the
programs from the printers software (clean the heads, centering the
articles, see if all the colors are displayed coretly...and so on), it
all WORKS.
So i came to the conclusion that somwhere in the link between printer
and my computer(relativly new dual core Pentium with 2 GB RAM, and
running on XP.
My question is? Does anybody know what am i talking about(maybe you
have a simillar problem yourself), and how to print like a normal
human been?

P.S. - I have all the latest drivers, and interesting anough the
printer work just fine on my stepfathers Macintosh, and a friends
laptop.

If i asked this question on a wrong place, please redirect me to the
real stuff.
Thank u all very much.
