In May I installed Ubuntu Mate 16.04 on my Toshiba laptop.
I installed software for my Epson Stylus SX420W with:
GDebi epson-inkjet-printer-nx420_1.0.0-1lsb3.2_amd64.deb Run cups 2.1.3 by browsing to localhost:631 Adding Printers and Classes -> Add Printer -> Discovered Network Printers -> Epson Stylus SX420W (without MAC address suffix) etc..
The Printer Test Page on plain paper for this was fine (possibly the red had just a touch too much yellow in it).
During the summer holidays I took my laptop with me and installed various printer drivers at different places:
Use cups to install driver for WiFi printer HP Deskjet 3050A
(but yellow comes out as dirty mustard colour, the cyan and magenta also come out darker than normal, the RGB are also of course darkened, the grey scale steps are darker than normal and the black is a very good black (better than my Epson black))
Use USB cable to connect to Canon MG6800 printer; system automatically installs CUPS+Gutenprint driver
(but yellow comes out as dirty mustard colour etc (as the HP above))
This is not a problem for other computers using the printer.
Use USB cable to connect to Canon Pixma ip3500 printer; system automatically installs CUPS+Gutenprint driver:
Later, back home again using the Epson Stylus SX420W:
