I have a new windows 7 computer and a hp officejet j5780 all in one printer I can fax but not print... please help

follow the link you find all you need in the page
download driver

If you have the HP Officejet j5780, you can download the full software and drivers that work with Win7. Go to http://h10025.www1.hp.com/ewfrf/wc/softwareCategory?lc=en&dlc=en&cc=us&lang=en&product=3301296& and select your OS version (32- or 64-bit).

Unplug the data cable and uninstall any generic driver if you plugged the printer into the computer (USB) before installing the latest software.

I hope this helps.
