I have a Hp designjet 430 an when I try to print I get the following error Error writing to LPT1 test page device not connected retry or cancel the job. I have a deskjet 610 and it is printing fine with usb connection. I have checked to make sure the ports are enabled in bios and device manager I have also install another paralell card and receive the same error on it. The pc sees and installs the printer with no problem but will not print.
