HP Laserjet M102A printer suddenly stopped working

[WM7793]

I had posted this in the wrong area of the forum, and I wonder whether you could please help me.

My HP Laserjet printer, model M102A has suddenly stopped working. I started having some issues where i had to release the printer via the settings to enable it to print out, But now it has stopped working entirely.
I have reinstalled the driver via HPLIP to no avail. Even tried the updated version from the software repository.

I afraid I am no wizard when it comes to deciphering information from the terminal but I will copy and paste it here for the well respected Linux coders to hopefully pinpoint the problem. (The triangle light on the printer is constantly flashing, but i have been through the HP simple fault finding guide with no luck.)

I would be most grateful for any help on this matter.

Best regards,
Clive

There is something weird going on here!

Just logged on today and the printer is working just fine. I tried rebooting the PC last night to see if that would clear any fault, prior to asking for help on this forum.

I realise that at the moment nobody has been able to help me with this matter, and I hope that it is just a case of an anomaly.

Best regards,
Clive

ps meanwhile, if somebody is able to make out something from the terminal information I posted in my original post it would be most welcome.
