MFP M234dwe printer. Connected to house network. PC says it's offline. 79 showing on the display

[frankmand]

My printer has, suddenly, gone offline. The light panel on the front is flashing orange. It's showing 79 on the LCD panel.

Does anyone have an idea what the problem is?

Thanks

Let's start with a Printer Reset

(1) Turn the printer on, if it is not already on.
(2) Wait until the printer is idle and silent before you continue.
(3) With the printer turned on, disconnect the power cord from the rear of the printer.
(4) Unplug the power cord from the wall outlet.
(5) Wait at least 60 seconds.
(6) Plug the power cord back into the wall outlet.
 NOTE: HP recommends directly connecting the printer power cord to the wall outlet.
(7) Reconnect the power cord to the rear of the printer.
(8) Turn on the printer, if it does not automatically turn on.

The printer might go through a warm-up period. The printer lights might flash, and the carriage might move.
Wait until the warm-up period finishes and your printer is idle and silent before you proceed.
