Network printer wasn't working

I’ve been trying to get my Brother 7065DN printer to work under LEAP. For several days I couldn’t get it to do anything. I finally did “zypper ve”, which solved the dependency problems I suspected, and the printer now works. But the printer log still shows something very odd:

Why am I getting these error messages? What should I do about them?

I get the same (re the cups-brf virtual backend for braille printers), and to date have just ignored them.

There’s a bug report for it here…
https://bugzilla.redhat.com/show_bug.cgi?id=1657261#c1

CUPS is reacting to ‘Get-Devices’ request, which starts cups-deviced binary, which starts every backend and returns all printers found by backends - cups-brf is needed to be run as root to work correctly (probably I can fix it in cups-filters) and gutenprint52+usb is probably called incorrectly or cannot cope up without any existing gutenprint supported printer. I’ll get to it when there are not more urgent matters, I’m sorry.
