Hello Michaelk,

I could only run the first code in the link with the following result

master@hal:~$ mv /etc/cups/cupsd.conf /etc/cups/cupsd.conf-orig
mv: cannot move '/etc/cups/cupsd.conf' to '/etc/cups/cupsd.conf-orig': Permission denied
master@hal:~$

That indicates that hp-setup was likely run without installing hplip-gui first. That is a must, and you do not say it was installed.

Another very real problem appears that you are running python 2.7. I believe the latest hplip uses python 3, and the install of hplip-gui for me installs several dependencies of python3 and qt5 packages.

Maybe you need to do a full upgrade.
sudo apt update
sudo apt upgrade
sudo apt install hplip-gui
then try hp-setup again.

Hello Michaelk,

I tried it again with the sudo on both instances

master@hal:~$ mv /etc/cups/cupsd.conf /etc/cups/cupsd.conf-orig
mv: cannot move '/etc/cups/cupsd.conf' to '/etc/cups/cupsd.conf-orig': Permission denied
master@hal:~$ sudo mv /etc/cups/cupsd.conf /etc/cups/cupsd.conf-orig
[sudo] password for master:
master@hal:~$ sudo cp /usr/share/cups/cupsd.conf.default /etc/cups/cupsd.conf
master@hal:~$ systemctl start cups
master@hal:~$

You need to use sudo because /etc/ requires root privileges.

Have you verified the contents of your cupsd.conf file yet?However, before making any changes verify the contents of your /etc/cups/cupsd.conf file.
Is it one line or a bunch?

Be sure to check the status

sudo systemctl status cups

Hello Michaelk,

Thanks you for the suggestions. I finally was able to enter localhost:631 and installed my printer. I have already printed some pages. However I need to fix the printer itself because it is missing every other line.
I really appreciate your help.
Best regards

Hello Computersavvy,
Thank you for your pointers. I have Python 3 installed because I have been writing a small program in that language.
