I have a problem with a Brother multifunction which has worked for 3 years and now will print but not scan. See: https://lists.fedoraproject.org/archives/list/users@xxxxxxxxxxxxxxxxxxxxxxx/thread/UU7A5X3FBHTXJPJVDXLTTCCIGYTS7CSI/#ENSCQUXN5RSIIH6EITGXNK7DVHBJDHVQ I have also reported it to BZ: https://bugzilla.redhat.com/show_bug.cgi?id=1444619 I agree it may be a firewall problem, but opening port 631 makes no difference whatever (and as I say, the print function was already working). poc _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx
