HP OfficeJet Pro 8720 USB not working

[rih5342]

When I connect the USB cable, the computer doesn't "see" the printer, it's not there.

I've tried 3 computers, 2  W10 machines and 1 mac, no luck

I've tried power cycling, rebooting.

The cable is fine, works on another printer.

Two tech support people have tried getting the printer on line, no luck.

Is there a way to  totally reset the printer?

Good day. Thank you for posting your query in the HP community. I will be delighted to assist you here. Superb description of the issue. kudos to you for that.

The USB port on the printer should be faulty as you've tried different computers and the USB cable works on a different printer.

This printer comes equipped with wireless and ethernet support. So try these steps:

• Perform a hard reset on the printer from this link: https://support.hp.com/in-en/product/hp-ink-tank-wireless-410-series/16180953/model/16180954/documen...  perform steps from the section “Step 1: Reset the printer

Then uninstall and reinstall the pritner at the root level by following these steps and use an ethernet cable to do it. You could go wireless also.

• In Windows, search for and open Programs and Features.
