Well despite all the helpful hints and comments I still decided not to give up. I went To the HP technical support site. entered my printer model no Deskjet 920c and and wasm directed to that site . thereit was how to install a 920c into Win7 . it required me to download the HPinstall Wizard for Win7. after installing the wizard, it told me to uninstall the 920c, reboot win 7, connect the power to the Lp and then connect the usb cable. It installed the lp again. i then selected the Lp service page, "cleaned" the cartrides AGAIN and then when ity printed the test page EURIKA!!! it had printed in color. so now it is working perfectly in color, balck & white & grey Scale. Perhaps somebody should tell hp "helpdesk" maybe its not too late to inform that KATHY in that attachement 137089 that she need not buy another LP but that she was given DUFF ADvise! I mention all this so if anybody else has the same problem , maybe this will help ?
