Using Ubuntu 16.04 lts

The printer use to work, but now in document print status it simply shows the print jobs have "stopped."

The printer is the HP Laser Jet Pro MFP M127fn

I did a fresh rein-stall of 16.04 lts,and that's when it quit working - perhaps I need to use terminal to reinstall something with HP involved?

If this is a new install you would need to configure the printer from System Setting or by using CUPS. For CUPS, in a web browser just enter: localhost:631 and add the printer.

What does the following report?
You could try removing any stale/stuck printing jobs...
and re-enable the printer (using name of the printer as reported by lpstat)...
then try printing again.

Please define "fresh rein-stall".

Also check the cups logs for errors. The printer requires a plugin and maybe it needs to be reinstalled.

I did a fresh reinstall of Ubuntu 16.04 lts from a thumb drive.
The printer is being recognized, but in document print status the task at hand is either "stopped" or indefinitely "pending"

I have canceled all print tasks and printed again with same results.

To reinstall the plugin you need to run hp-setup.

The min version of hplip required for your printer is 3.13.11.

Is taking forever and keeps graying in and out like the cpu is having problems - probably time for a new computer. This is a Core 2 duo

You might try it running from a terminal window.

Please provide the exact lines I type in terminal. I'm really a newbie when it comes to these things.

Thanks in advance for all help.

I understand.

https://developers.hp.com/hp-linux-i.../install/index

Reinstalling (via hp-setup) is probably a good idea. I note that you have two printer queues defined for the same printer...

For HPLIP printing only the second is valid. You'll note that it's using the 'hp' backend, whereas the other is using CUPS 'usb' backend and should be removed.

The following should have been enough to re-enable the print queue though....

I'm on step 8 of the terminal install now - will report back in a few on how far it takes me. Smiles

Well, I got to this point in terminal and apparently suffered a failure where you see *error* below:

Unplug and reconnect the printer physically and check output of
