Printing Errors or Lights & Stuck Print Jobs

My all-in-one deskjet printer has all of a sudden stopped working. It says it is connected to the internet but the HP smart app says it is not connected along with stating that I am not using HP Instant ink (I only get my ink from HP Instant ink). The light is on for the ink even though I took my newly replaced cartridges out and put brand-new ones in. The paper feeder light is on even though it has paper and I have pushed it multiple times. The information button is blinking and prior to it completely tanking, it kept printing the printer information page, which the pin number does not match the pin on the printer.  The wifi light is solid and my computer says it's ready to print but it never prints and does not copy either. I don't constantly use this printer, so there is no reason for it to be broken in 2 years of light use. I have done all the solutions recommended by HP with no success. This includes disconnecting the printer and router and running diagnostics on the printer which gets stuck at test print. I have made sure the operating system on my Mac is up to date and the firmware on my printer is current as well. I have tried uninstalling and reinstalling my printer with no success. The HP smart app will not and has never allowed me to finish the setup process of my printer either. Of course, my warranty expired a couple of months ago on my printer so it's obviously not covered anymore (convenient). Any suggestions on what this issue might be? I have had nothing but issues with this printer since the day I bought it! Ugh!
