Greetings! This is my first post. I hope I'm doing it right, and please forgive me if I'm not.
I have installed GUIX (including CUPS) onto a Lenovo ThinkCentre P520c, successfully except that I cannot print from within the Guix installation. I have a trusty Brother HL-5350DN laser printer connected via ethernet to my local network. Pointing the browser to http//:localhost:631 brings up a CUPS interface, but produces an error message: "The web interface is currently disabled. Run "cupsctl WebInterface=yes" to enable it." I try that but "command not found". Commands I have used like 'systemctl start cups.service' etc don't work on Guix either. Is there a Guix equivalent? Attempts to enable the Web interface via the config.scm (GNU Guix Reference Manual 10.8.7) have also failed. And yet: if I type the IP address of the printer '192.168.1.108' directly into the browser, it shows up as "http://192.168.1.108/printer/main.html"; and I find myself in a Brother utility for the printer, from which I can successfully do a test print. The Brother utility has a number of screens: Home Page, View Configuration, Maintenance Information, Find Device, Printer Settings, Administrator Settings, Reset & Test, Network Configuration. This ought to be encouraging, but when I attempt to print a working text document (e.g. via Gedit) although the printer is listed (along with IP address and all usual data) it says "Processing - Not connected?", despite the system clearly knowing the address etc. I set the printer up normally in Gnome Print Settings, but if I look at the View Print Queue, it says "Document Print Status: Processing - Not connected?". If I go into Server Settings to check the 'Publish shared printers connected to this system' setting the troubleshooter recommended, I get "CUPS server error: There was an error during CUPS operation: 'Failed to set settings'". Troubleshooting's final verdict is "There is no obvious solution to this problem." I'm foxed, and frustrated, and as a desperate work-round I have to ssh the file to another machine to be printed. By the way, I have successfully set up printing for MacOS, nixOS, Debian, and Arch, but GUIX (alone) fails to find the printer, except via the Brother utility. Any clues? I earnestly want this FSF-endorsed distribution to work. I'm including my config.scm, and the troubleshooting report.
