HP1012 on Ubuntu 16.04
Did an update on the OS and the HP1012 would blink green light and nothing else when tried to print or self test print.
Removed printer, and ran hplip.run, and re-installed printer. Now it prints a blank page in Self Test from Ubuntu.
Long pressed button on the printer itself and Voila! Get a successful self test print out. Changed out cable and different USB port and still blank self test from Ubuntu.
THE FIX:
To install the latest version of HPLIP driver by using a PPA, execute the following:
* open a terminal (Applications > Accessoiries > Terminal)
* type the following command: '''sudo add-apt-repository ppa:hplip-isv/ppa'''
* press Enter and if needed, type the required password
* type the following command: '''sudo apt-get update'''
* then type the following command: '''sudo apt-get install hplip'''
Now when I did above, it now asks for a self test print out and it works. Now prints any document, no problem.
