Re: HP Officejet K7100 not printing
Power off and disconnect the printer, Uninstall the software/drivers using Add and Remove programs, and then delete any remaining printers (Officejet K7100, officejet K7100-1, officejet K7100-2) listed under printers and reboot.
After Windows has rebooted, reinstall the HP software/drivers using the installation CD. Follow the prompts and connect the printer when told to do so. When it's complete, you should get a test print.
