I have installed CUPS on my Pi 3 B + and can print a test page from another computer using the CUPS web administration on https://192.168.0.20:631 from the Administration. Manage. Maintenance.Print Test Page option. This works fine to my SAMSUNG SCX4623 network printer on 192.168.0.203:9100 so CUPS seems to be working as is the PPD and the network connection to the printer. However, when I look in any of the XWindows apps eg Libre Office Draw, the printer is not offered as an option and hence I cannot print to it. The only printer offered is a 'generic' and this does not work.
How do I install the printer into the XWindows apps?
A simple guide added to the documentation on how to set up printers would be most helpful together with copies of screens.
It seems strange that such a useful computer is missing something as fundamental as printer support!
When will it be added to the distro?
