With the latest printer firmware, the default username remains admin (all lower case), but the password is the WPS PIN Number. To locate the WPS PIN Number, print a Network Configuration Report and locate the PIN Number within the WPS Information section.
Turn the printer off (using the power switch at the back of the printer), wait 15 seconds and turn the printer on. The error should disappear; however, if the error does return, turn the printer off and plug the power cord into a different power socket.
If your printer`s status displays “Printer in error state,” there may be a problem with the printer itself. Make sure the printer is turned on and connected to your PC by Wi-Fi or cable. Check it for low paper or ink, and be sure the cover isn`t open and the paper isn`t jammed.
Restart your computer, and then immediately press the F11 key repeatedly. Click Start . Press and hold the Shift key, click Power, and then select Restart while holding the Shift key.
Click the Start, Control Panel, Printers, and Faxes. Right-click the printer driver and select Properties. Click Ports, Add port, Standard TCP/IP port, New port, and click Next the TCP/IP printer port wizard to provide the IP Address of the printer. Click Next and Next again.
1. Paper Jams. Paper jams are a common problem for printers, resulting in time-consuming and frustrating delays. It can occur when loose sheets of paper get stuck in the rollers or feeding mechanism of the printer.
For anyone else who finds this page when tracking down this error, Error 79.8109 is simply the result of using the wrong printer driver (i.e. the HP Universal PCL6 driver, as provided under Windows 8 and 10). This driver does not work correctly with this printer. In general this error isn`t a formatter problem.

What repair needs to be done for a "50 needs repair" message on an HP Laserjet IIIP?
ANSWER : I don’t know what you mean by good toner cartridges. They haven’t been built in about 10 years, so if they are new OEMs in the box, they are guaranteed to fail. The 50 error on that printer is mostly a burned out fuser lamp. This site was sold, so as you can see, there are no more kits available.
