Hi FrankieBoy2,
First we need to determine if you are having a hardware issue with the USB port on the printer. Please connect the printer to a different computer, and let me know if you are able to detect the printer, and get it installed?
What is the operating system on your computer?
Have you tried different USB ports on the computer?
Do you have a USB hub between the printer and computer?
HP designed a quick and easy tool that diagnoses and resolves many printing, scanning, and connectivity problems: The HP Print and Scan Doctor. HP recommends that you download and install the Print and Scan Doctor any time you need to troubleshoot a problem with your HP printer from the link below.
Let me know what errors you receive?
