Answered in your duplicate post before I saw this one.
(is here correct section for this post?)
i have linux Mint 18.3 based on Ubuntu.
till yesterday my Xerox Workcentre 6605DN was working properly with a driver i found in linux mint database
I had use driver for Workcentre 7345 without any problem....
i had install last firmware from original of 2012 to the last of 2016
Now under windows the printer work normally as usual but under linux not work
linux (i had try several drivers) see the printer "offline" and noone job sent is printed.
i had try xeroxprntmng in text terminal, i had try there several drivers... noone work
so i have 2 solutions:
1) find the old firmware
2) find a working driver....
can someone help me?
