Printing Errors or Lights & Stuck Print Jobs

I'm trying to troubleshoot a wifi connectivity issue with my printer.  The printer turns on, and it immediately displays the message 'Cartridge cannot be used until printer is enrolled in HP Instant Ink.'  The next message is that it tries to print a test page, which it can't do, so the display either remains attempting to print an alignment page, or it reverts to the HP Instant Ink message.  Failure! Failure! Failure!!!

The problem is, the printer cannot connect to my wifi, and I cannot get the menu display on the printer because of the error message, which won't resolve because the next problem is that it I'm not connected.  I have tried disconnecting and reconnecting numerous times.  I've tried rebooting the printer, the wifi, and the computer numerous times.  I tried updating via USB cable, and so on.  I have tried updating the drivers and the firmware.  The virtual help desk is worse than useless because it presumes I can print a printer information page, which I can't due to the instant ink restriction.

My next try will be to replace the HP Instant Ink cartridges with ones that I buy off the shelf today.  At which point I will cancel my subscription to Instant Ink.

My question is how do I cancel my subscription?  This issue has shown that instant ink is great until it becomes a miserable failure in that it interferes with troubleshooting.
