When is the last time you have used the printer? If you have not used in it 6 months plus, the ink cartridges can dry up. Try taking one out, use a cotton swab and some rubbing alcohol gently to break up the dried ink. reinsert, and try again.
If not, it sounds like you need to reinstall the printer drivers.
Did you remove the protective tape from the ink cartridge heads? <grin> Seriously though, what hodmokrin stated above is a very common reason for this problem. I would add that most printers have a way to invoke a built-in self-test printout.
If the printer prints this self-test page correctly, then the problem is not in the printer. Keep in mind this is not the same as the Print Test Page option in Windows. The printer self-test should be able to be performed from the printers button controls without even being hooked by to the printer.
If the self-test also results in a blank page then the problem resides in the printer. In addition to hodmokrin's instructions, also clean the copper/brass print head contacts in the same manner. Finally, if no joy... try a new cartridge.
If the self test page was successful, then proceed to try to print a Test Page from your Printer and Faxes Control Panel Option in Windows: Start->Control Panel->Printers and Faxes->right-click on your printer icon->select Properties->click on the Print Test Page Button. If this produces a good printout, then the problem is in your application (ie: Word or such). If you do not get a good test page, I would recommend uninstalling and reinstalling your printer software.
Sorry. Forgot to post the self-test instructions. I found these on the web, so if they don't work then you should consult your manual.
1. Make sure the printer is off but is plugged in
2. Hold down [RESUME] (Triangle pointed down) and hold down [POWER]
and wait 5 seconds or so.
Release [RESUME] but Continue to hold [POWER]. Double click [RESUME].
then Release [POWER].
Press [RESUME], than [POWER]. This should cause the printer to print a
simple diagnostic that'll list it's ROM number and list CDR SENSOR=OK
in red for the last line.
Press [RESUME] twice then [POWER]] to print off the second diagnostic.
Press [POWER] by it self to exit service mode and return to being a
