I am using a usb HP Laser Jet 1200 printer and I cannot get it to install. How do I install the laser ? I have four units connected to my USB ports. The HP Photosmart 7650 printer,
my HP scanner, my 7-1 usb reader and and my HP printer. I didn't try and install the HP 7650 printer and it was off when I tried installing my laser. Hope this info helps.

Thanks

Arthur
