These are to a test PC. The HL5470DW was set up on my main PC running whichever Leap was installed at the time, possibly 42.1, which has been upgraded to each subsequent release through 15.1, and it's still working as expected. https://en.opensuse.org/SDB:Brother_How_to_setup_a_Networked_Printer_Scanner shows last tested with Leap 42.1. :( Two different Brother IP printers connected via ethernet: HL-5470DW MFC-8910DW Each is configured with a static IP (V4 only, same as rest of LAN). I installed all supposedly appropriate drivers from Brother website using zypper, which pulled in cups and other deps, successfully AFAICT: # zypper se -si 8910 5470 ... i+ | hl5470dwcupswrapper | package | 3.0.0-1 | i386 | (System Packages) i+ | hl5470dwlpr | package | 3.0.0-1 | i386 | (System Packages) i+ | mfc8910dwcupswrapper | package | 3.0.0-1 | i386 | (System Packages) i+ | mfc8910dwlpr | package | 3.0.0-1 | i386 | (System Packages) YaST2 found both printers, and apparently accepted their setup without error messages. SeaMonkey found both printers' web pages by IP address, reporting in sleep mode, and no option for printing a test page that I could ID. Print test pages failed for both. /var/log/cups/error_log: E [04/Dec/2020:01:16:20 -0500] Unable to open listen socket for address [v1.::1]:631 - Address family not supported by protocol.

I then tried using Brother's Linux installation script. This produced two symbolic link already exists errors, an unsupported document format error for "text/plain", and no such file or directory for /etc/sane.d/dll.conf, plus the test print pages never materialized. Afterward, YaST2 reports 2 of each printer, so 4 in total. I tried opening http://localhost:631/admin to see the same 4 printers, with 3 idle, and one 8910 status "unable to locate printer "BRNMFC8910", which I then canceled. I then tried to print a test page, and received a no such file or directory error. Tail of /var/log/cups/error_log then contained: E [04/Dec/2020:02:55:43 -0500] [Client 210] Returning IPP client-error-document-format-not-supported for Send-Document (ipp://localhost:631/printers/HL5470DW) from localhost E [04/Dec/2020:03:12:09 -0500] [Client 237] Empty Basic username. E [04/Dec/2020:03:12:11 -0500] [Client 239] Empty Basic username. Same result for the other printer. # journalctl -b | egrep -i 'ailed|rror' produces nothing related to any printer, as dmesg shows, unless 'broken atomic modeset userspace' counts. Where to I go from here? Is this a YaST2 thing? Basesystem? Cups? Deps that are missing from Brother's rpms? -- Evolution as taught in public schools, like religion, is based on faith, not on science. Team OS/2 ** Reg. Linux User #211409 ** a11y rocks!
