  1. Hi please see below output of sources list ref. the problems involved. Its difficult to understand why a line referring to a print driver could cause so many problems. Any help would be appreciated.

    cat /etc/apt/sources.list
    Line 129 deb http://download.ebz.epson.net/dsc/op/stable/debian/ lsb3

    Malformed entry 129 in list file /etc/apt/sources.list (Component)
    E: The list of sources could not be read.

    Then: Failed to load the package list This is a serious problem. Try again later. If this problem appears again, please report an error to the develop

    MORE ERRORS

    gedit:6705): Gtk-WARNING **: Calling Inhibit failed: GDBus.Error:eek:rg.freedesktop.DBus.Error.ServiceUnknown: The name org.gnome.SessionManager was not provided by any .service files

    im not sure if the amendments I made were saved as when clicking "save" there were no options for a destination to save to. Is it possible to rebuild the repositories please. If so how?

    thanks

    Hi 'justmaggs', Have you had success using your Epson printer with Ubuntu before?
    I don't know which printer you have, but I checked on the Epson site, and they don't seem to provide drivers for any Linux distros.
    Normally you would find the information from the maker's website, and copy and paste the line into the 'additional software sources' in Ubuntu.

    Hi mike. thanks for your reply. Yes Epson printers usually work straight "out of the box" on linux distros. My printer was fine on ubuntu 13.04 & 14.04 but had a problem with the latest Ubuntu 16.04. Anyway I have sorted it now there was a filter file missing from the ppa repositories. D/l it and hey presto all working. Thanks for trying to help. cheers

    Hi, Good to hear it worked, Linux distros such as Ubuntu and Mint are usually good in providing drivers for monitors, keyboard mice etc, I normally don't have any trouble, but printers can be left behind when newer software is released.
    I replied to this because I have just installed U 16.04 RC (last beta) after using U 12.10 for a couple of years with very good results.

    Hi No problem getting the driver 201202w printer set up found it right away but it was missing the filter that released the jobs to print. deleted the printer d/l the driver from epson, installed via cups still no good made worse by Ubuntu wanting to use the epson driver for xenial but it was not ready even when letting cups find & install. I heard it was missing a lsb package. installed this, still no good. Lots of conflicting advice on forums
    that obviously worked for some people but not me. Anyway the end solution was really easy, the filter was hiding in here

    sudo
    apt-get install printer-driver-escpr
    and then add printer select type of connection DNS-SD and then ESC/P-R (This software is a filter program used with the Common UNIX Printing System (CUPS) under Linux. It supplies high quality printing with Seiko Epson Color Ink .)

    Thanks again for your interest

    Harry forgot to say: switch printer off : delete printer: Do sudo as above: switch printer on: Go to add printer and let the set up do the rest. I did not have to use ESC/P-R

    Hi, There is some good information on the Epson site;
    http://download.ebz.epson.net/man/linux/escp.html
    (Esp. points 5,6 etc.) Thanks Epson for that.
    But I have found that whenever a new version of an O.S is released,(of any variety) that the printer drivers for it, tend to be released many months later, and if the printer or scanner is more than a few years old, may not be supported at all.
    New printers usually will have a printer driver on CD supplied, which could be useful, if the correct O.S, or slightly out of date.
    I have tried several Linux distros where my Acer monitor was not supported, and I had to change distro purely for that reason.
    I found Ubuntu (and it follows, Mint) are better than most and they automatically detect my setup on installation.
