I'm not completely certain, but I'm wondering whether it's possible to print IPP Everywhere at all, if DNS-SD or WS-Discovery aren't working on the client. Even having the IP address might not be enough. I guess one way to test it would be to run the printing test case with an IPP Everywhere printer, and try to print with avahi stopped. -- Chris Murphy _______________________________________________ devel mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@xxxxxxxxxxxxxxxxxxxxxxx
