That's likely part of the issue but I think there is more to it due to the discovery issue; more details about that below: I also have a HP Color Laserjet 2550L printer hooked up the same way as the Xerox Phaser 3250. I moved both printers to the Centos 6 machine and neither one of them were "discovered" by the Centos 7 machine. Both of those printers showed up by magic as discovered printers on the other Centos 6 machines. When the printers were hooked up to the Centos 7 machine, they weren't automatically "discovered" by the Centos 6 machines. I set up those printers this morning as shared printers on a Centos 6 machine and there was no further configuration required to get them to show up and work on the other Centos 6 machines. In order to get them to work on the Centos 7 machine, I had to "search for printers" and specify the hostname to search with system-config-printer. They then showed up but the test page didn't print properly using the default settings and I had to change those settings as described in my previous message to get the test pages to print. I find it curious that nobody else seems to have encountered this problem. That make me suspect that cups is mis-configured on Centos 7 in a way that affects both printer discovery (incoming and outgoing) and the printer driver. For another example, I occasionally get the message "connecting to printer" when printing from Centos 6 to the printer on Centos 7 (and no print-out); that doesn't happen when printing from Centos 6 to another Centos 6 machine. -- MELVILLE THEATRE ~ Real D 3D Digital Cinema ~ www.melvilletheatre.com
