Greetings,
We know what the problem is and the model of printer you own, but little more.
How the printer is connected and to what?
OS you are using the printer with?
Drivers you installed?
Did it ever work?
What changed?
Etc...
"attempting numerous and repetitive fixes".. I'm afraid this doesn't tell us what you did, or what happened when you did it. Troubleshooting steps? We canoot make suggestions if we don't know what actions were performed.
