To add a printer to your System76 Computer, click the Ubuntu icon at the top left of your screen and type the word Printers then choose the Printers application in the search box. In the Printers Application, click the Add button and a box will pop up with different options. Wait a few seconds for printers to appear in the Device List.
Select the correct printer and click Forward. The computer will search for the correct Drivers to enable the printer. A box may come up that says ‘Installable Options’ which you can select any other options available for your printer and then click Forward again. Name your printer in the next dialogue box and click Apply. A prompt to print a test page will appear next.
First in the Software & Updates settings go to the Other Software tab, and check the first item, Canonical Partners. Then, after closing the Software & Updates program, add the driver with this command:
sudo apt install lsb printer-driver-escpr
And when adding the printer, select type of connection as DNS-SD, and then Forward, and then ESC/P-R.
If the printer stops working, open the Printers Application again and right-click on the printer and select Delete to remove the printer and its settings. Repeat the steps above to add the printer and try printing the test page again. This process usually resolves many printing issues.
To look at the CUPS (Common Unix Printing System) configuration and status window, please open this webpage:
The status window will show current print jobs, detected printers, and other information about the printing system.
sudo apt install --reinstall cups cups-client
This will reinstall CUPS, the main printing software, which can help with generic issues.
sudo apt install --reinstall system-config-printer-*
This will reinstall the system control panel if the settings are not available.
