+ 0 Votes Did you connect it to the 2nd computer? ThumbsUp2 5 years ago I presume the first install went fine because it's physically connected to that computer. Did you try physically connecting it to the 2nd computer? If not, you shouldn't be trying to run the installation software. You should be adding a printer which is shared from another computer and providing the drivers ONLY when asked to do so. + 0 Votes If Jacky's posts 2.1.1 & 2.2 don't help seanferd Updated - 5 years ago try scanning for malware.

The fix I used was to remove references as stated above. After that I uninstalled the USB ports. re-scanned for the ports and plugged in the printer. The install went fine after that, both times I have tried it. + 0 Votes Have a look in your BIOS.....
