HP LaserJet 4050 Printer Questions & Answers
Printer does not print and shows printer error 79.8109

some things you can try. You may need to clean and/or replace various parts in the paper path, starting with the feed rollers.
The only mention I found for 79.x errors refer to a faulty formatter board. If that is your problem, then you will need to replace it. But I suspect you can get newer and better printers for less than the formatter!
Before you replace it, try a cold reset on the printer, to reset everything to factory defaults, like this:
Remove the Jetdirect card. Turn printer off. Hold the GO key. Turn printer on. Continue to hold the GO key until the printer reads COLD RESET. Release GO. INITIALIZING appears. Then RESTORING FACTORY SETTINGS Followed by OFFLINE. Press the GO key to put back on line. Switch off and reinstall the Jetdirect.
PCL XL ERROR
Bad adobe command. Try printing as image in the print driver or using a PS driver.
Why has it stopped printing manual feed?
Does the printer try to feed the page and does not?, or does the mechanism not engage at all. If it tries to feed and is unsuccessful then based on the age of the printer likley the manual tray pickup roller is worn out and the separation pad is likley bald as well. You can use the paper path test to confirm if the tray is working at all. That would really be the first place to start.
