I have installed Ubuntu 12.04. My computer no longer recognises my laser printer - Samsung CLX-3175 - and will not install the drivers, refusing to run the scripts downloaded from the Samsung site. How can I fix this?
This printer should work with the Samsung CLX-3175 Foomatic/foo2qpdl driver included with Ubuntu.
Go to system-config-printer (System -> Administration -> Printing in GNOME classic, Gear icon at the upper right of the screen -> Printers in Unity), right click your Printer and select Properties > click Change... next to the Make and Model field to see the available drivers and change it to Samsung CLX-3175.
Normally your printer should automatically get set up with this driver when first connected with USB.
