Printing Errors or Lights & Stuck Print Jobs

My Envy 4500 all in one inkjet needed a new black cartridge. ( I use only one cartridge mode--no color)

I ordered the replacement from HP, got it in two days, replaced it. I have replaced cartridges many times. When I went to print, it gave me a pop up saying cartridge was depleted. It wasn't. I tried another new cartridge, since I had two. Same thing.

Checked all settings, reinstalled software, same error.  Put in a color cartridge as well, just in case, no change.

Unplugged and plugged back in ten minutes later--it printed the document that was in queue.

Now, whenever I want to print something, I have to send it to the printer, then get the error message about the cartridge, then plug the printer in, and then it will print that one time, whatever is in the queue. If I then try to send something else to the printer, it will give me the error message again. This happens whether on wireless or USB.

So now, I just unplug the printer when I'm done printing and leave it unplugged. If I need to print I follow the above procedure, but this shouldn't be necessary and it's so inconvenient.

I haven't seen anyone with the exact same issue. Any idea? The printer is out of warranty. (of course!).

I want to mention just in case, I've always ordered ink from 4 inkjets, and I've never had an issue with the printer recognizing them, even though they are not HP. This time I figured I'd try genuine HP cartridges. 

Thanks for any light anyone can shed on this.
