In the Elive Retro 3.8.32 version, I had printer setup issues resulting in a CUPS internal server error.
For some reason, the CUPS driver information setup did not appear at all, and was bypassed somehow.
In the end I got the printer working by typing in the command system-config-printer, in the terminal. And this time the CUPS driver selector worked.
I was able to print a test page, and that was that.
