Question about UPS Battery Backup Systems
Windows not recocniz deskjet3420
Posted on May 29, 2008
The HP3420 is connected to your PC through the USB port and not through the LPT1/parallel port.
You have to change the port setting. Go to Start, Printers, right click on HP3420, click on Properties, go to the Ports tab, check/select USB, OK.
Alternately, you may have to re-install the drivers for the HP3420 and allow the program to Search for the printer connection. Clicking on the button Stop Searching will auto install it again to LPT1.
Hope this be of some help/idea. Post back how things turned up or should you need additional information.
Good luck and kind regards.
