Older iMac, sudden HP printer issues

I have a mid-2010 27" iMac running macOS Sierra v. 10.12.6. At the time I purchased it, I also bought an HP Photosmart C4780 printer (scans, copies, prints, no fax). The only issue I've had with the printer in the past was it would not work wirelessly, so I have always had it connected via USB, no biggie. Suddenly, I am unable to print anything at all. I've completely reloaded the HP printer disk, and still no printing. I am unable to upgrade the OS. Has anyone any suggestions, please and thank you?

My apologies, in my original post I meant to input HP. You are not being obtuse, I just goofed. I meant to write:

·Uninstall all HP software, put in the Trash and empty the Trash.

·Please reset the printing system per Reset the Mac printing system to solve a problem

·Next, follow the instructions in Adding a printer

Ok, sorry to sound obtuse, but the only Canon software I have on my iMac is for a digital SLR camera. I need to uninstall this software and follow your other guidance? Will I have more printer issues if/when I re-install the camera software? Thank you again!

Oh gosh, I wish I could say this worked. Perhaps I should have tried wireless, but I've been using via USB for years without issue. I can't think of anything else to try. Panicking now!
