# lsb_release -rd
Description: Ubuntu 19.04
Release: 19.04
###-----
### NOTE starting point
###-----
My printing system for the last 12-15 years based on cups had/has the following
setup:
* 1 network laser printer "Brother MFC 9142CDN"
* 3 "symbolic" printers which are copies of the former, configured to set
defaults for particular uses: "monoprinter" (grayscale), "colorprinter" (full
color) and "labelprinter" (use of manual feed)
The "Brother MFC 9142CDN" was instantly discovered and completely PPD
configured and successfully tested with a fresh Lubuntu-19.04 install,
last week.
###-----
### NOTE by request: see attachment for "ubuntu-bug cups" output
###-----
###-----
### NOTE After first install and fresh configuration my printer setup looks as
follows
###-----
