I have no idea what is wrong here. Have been printing just fine for several weeks now with Vista as OS. Suddenly won't print. Tried delete from Control Panel, reinstalled software/drivers. Now Vista shows this as the default printer with docs in que to print, but won't print. Printer is newly new. I am now downloading drivers from HP site, and will reboot. I am out of ideas totally. Also, turned off printer, unplugged USB, turned on printer and replugged the USB. Also rebooted 3 times. Any suggestions are most appreciated.
