From Wiki-Fou
There is an EPSON AL-C4100 at the hacklab. Here is how to use it from *nix systems (Debian, Ubuntu, etc.):
Install
# install cups
# run cups daemon
# go to localhost:631
# search admin menu, manage printers, add printer section.
# if you're connected to calaofu network the discovery process should be
automatic
# select from discovered printers one called EPSON_AL-C4100
# be sure to select proper driver (usually the recommended is fine)
# be sure in default options to select A4 as default paper size
# save everything
Print from command line
# take a look at cups command line docs for printing:
https://www.cups.org/documentation.php/options.html
# usually the process is:
## list printers
## print file passing printer as option
Print from Graphical User Interfaces
Should be simple, usually just use File/Print and select EPSON_AL-C4100.
