HP Photosmart C4780 All-in-One Printer
Microsoft Windows 10 (64-bit)

Hi, just as the title suggests I cannot print anything from my c4780 printer.

 

There were errors connecting it wirelessly which is fine, I bought a printer cable and have it hooked up via USB into my desktop. I ran it through Scan and Print Doctor, HP Smart, and no problems arose UNTIL I tried to test print. When I try to print ANYTHING WHATSOEVER, my printer takes in the paper like normal, and just when it's about to print, stops. The screen is constantly on the "Printing..." screen with the loading bar, but nothing ever happens, not even any sounds or movement from the printer.

HP Smart says my ink levels are fine, and both that and the Scan and Print Doctor say there are NO ISSUES when clearly there are, as I am not getting anything from it. It won't even give the piece of paper back until I click Cancel, and then it slowly discards the paper as normal. 

I restarted the printer and my PC many times, reinstalled drivers, deleted TMP files, removed the printer from my PC and re-added it, and nothing is working. Do I just have to go to a technician? 

Thanks in advance.
