Hello, I’m trying to use my Epson XP-200 printer/scanner with OpenSUSE Tumblweed.

  • /etc/sane.d/dll.conf has the “epson2” line uncommented.
  • /etc/sane.d/epson2.conf has “net autodiscovery” as its last line
  • My user is part of the “lp” group, which seems to be required for finding printers/scanners

If I disable the firewall completely (using YaST2 firewall program), it works – the Skanlite software detects my scanner and connects to it. With the firewall enabled, however, Skanlite says SANE cannot find any scanners. I have tried allowing TCP and UDP ports 8610, 8612 (based on suggestions from https://wiki.debian.org/SaneOverNetwork), and 631 (for CUPS) in the “public” zone, and added the “sane” service to “Allowed” services (didn’t see a “cups” service option), but Skanlite still says SANE cannot find the scanner.

Is there a way for “net autodiscovery” to work without completely disabling my firewall? What ports/services should I allow? It seems the alternative is to manually specify the printer’s IP address in /etc/sane.d/epson2.conf instead of “net autodiscovery”, but I would prefer to not hardcode this.

Thank you in advance for any suggestions!

      Added “mdns” service to allowed list for public zone, still get the SANE error. (Previously added 5353 UDP per another suggestion – sounds like this is the port for mDNS)

        A quick scan through the services in Yast firewall revealed that there is a sane service too. Is that enabled?
