So this is log about my experience with Epson L455 multifunction printer that I bought in Brazil.
Does it work?
Short answer: YES!
Not only I did setup the printer using only a Linux station with a Mozilla/Firefox browser, but I believe the information on the WEB and also on the "quick start sheet" that comes with the printer (in the box) it not clear about this. You do not need to use CD/DVD or the other paid OS.
Does EPSON support Linux ?
For my surprise and exactly what made me choose the EPSON printer was that it is really committed to support GNU/Linux users.
Check this (and choose Linux OS):
Does EPSON have good documentation to support Linux, see this:
And I notice support for not only Ubuntu 14.04 and 16.04 but for other flavors of Linux as well.
Does EPSON L455 scanner and printer work over wifi without the need of a USB network host computer ?
YES! But you need to install all the packages as describe in the documentation you downloaded, and also configure properly the network, printer CUPS and SANE conf file (all detailed in the documentation).
In less then 30 minutes I figured out (ie. followed the instructions) and was not only printing with quality control but also: scanning documents and changing the network DHCP IP to a fixed IP address using just the a web browser connected to the printer WEB-GUI. And also, don't forget to change the Admin password!
Does it work with Android, to print and scan direct to and from your phone ?
YES! But you need to download and configure from Google Play the EPSON iPrint app. Should work with iPhone too.
EPSON, THANK YOU!!!!!!
GNU/Linux community loves you!
