Hi, I have a LAN using CentOS and Fedora installations (currently its CentOS 7 on the server). At times it insists on doing double-sided printing, and will not let me choose single-side. Erratically the option is either unavailable (the drop down menu is not clickable, and says "not available"); or when the option is responding, my selection is ignored; and some days it works properly. The printer is a HP LaserJet P3015. I get this erratic behaviour on any of the PCs, and it used to do this, too, when the server was previously a Fedora install. Anybody have any clues? -- uname -rsvp Linux 3.10.0-1062.1.2.el7.x86_64 #1 SMP Mon Sep 30 14:19:46 UTC 2019 x86_64 Boilerplate: All unexpected mail to my mailbox is automatically deleted. I will only get to see the messages that are posted to the mailing list. _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-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/users@xxxxxxxxxxxxxxxxxxxxxxx
