Thread: Problem Configuring Samsung M2020W Laser Printer

    Question Problem Configuring Samsung M2020W Laser Printer

    Hello,

    I successfully downloaded and installed Samsung Unified Linux Printer Driver for Samsung M2020W Printer. The latest cups is already installed. Both power cable and printer USB cable are firmly connected to the printer. However, I cannot configure the printer for first use. I tried the following:

    1) Via Configure Desktop > Printers

    The "Password -System Settings" window asks for the root password. I enter my root password, but it says "wrong user name or password". I use the same password for logging into Leap, or YAST without any problems. This particular window keeps asking for password for user "root".

    2) Via YAST > Hardware > Printer Configurations

    The screen says "There is no print queue"

    I have successfully done this many times before in Leap 42.2, Tumbleweed, Fedora 25 and Debian 8 on the same PC. This is the first time I run into problems configuring Samsung M2020 printer in Leap 42.3. Any suggestions?

    Thank you for your help.

    What about cups?
    Code:
    localhost:631
    in the Browser.

    I use Firefox browser. How do I find localhost in the browser?

    Please note that both cups and ghostscript are already installed. All other Linux OS's including Tumbleweed, Fedora 26 and Debian 9 have the printer working.

    I got "cups 1.7.5" page after typing "localhost:631" in Firefox's address bar.

    Default Re: Problem Configuring Samsung M2020W Laser Printer (SOLVED)

    Hi everyone,

    I did change the root password as suggested in the link provided by deano_ferrari, but no go.

    Then I searched Google for the error message " Returning HTTP Forbidden for CUPS-Get-Devices (no URI) from localhost".

    Results from several years ago in Debian Forums suggest that the solution to the problem of

    Code:
    pam_authenticate() returned 7 (Authentication failure)
    lies in "lpadmin" group membership.

    After a few trials using YAST > Users & Group Management, I got the printer working as follows:

    1. Use the (new) root password to access YAST;
    2. Users & Group Management;
    3. Add "root" to "users" group (very important step, otherwise I keep getting "wrong userid or password" message)
    4. Configure Desktop > Hardware >Printers
    5. Manually Add a PPD File (since system fails to automatically detect my plugged-in Samsung printer)
    6. Search > Home directory >Downloads >uld > noarch >share. (ULD stands for Unified Linux Driver)
    7. Select PPD file name: "Samsung_M2020_Series.PPD"
    8. Select "Next"
    9. A dialog box appears bearing the printer's model name, number and other buttons to configure printer.

    Voila! PROBLEM SOLVED!

    Thank you Sauerland and deano_ferrari for your helpful suggestions!

    It's not clear to me why that was needed. I'm away from my Linux machines for the next few days so can't investigate further. Usually entering the credentials for the administrator (SystemGroup) defined in cupsd.conf should be sufficient. Maybe security setting related?

    Hello deano,

    I cannot open /etc/cups/cupsd.conf as root (I am the admin of my PC). The screen says "Access denied".

    What's next?
