I think the root cause is some change outside of CUPS and/or cups-filters (the latter contains cups-browsed) because as of today (03.Nov.2023) nothing changed in CUPS since 20.Sep.2023 and nothing changed in cups-filters since 17.May.2023, see https://build.opensuse.org/package/view_file/openSUSE:Factory/cups/cups.changes?expand=1 and https://build.opensuse.org/package/view_file/openSUSE:Factory/cups-filters/cups-filters.changes?expand=1 To debug certain network printing issues https://en.opensuse.org/SDB:Printing_via_TCP/IP_network could be somewhat useful but it depends on what the root cause is why printing via network fails, e.g. when the reoot cause is a generic networking issue then generic networking debugging would be needed.
