I have reconfigured one of the 3 copies cups discovered for ipp-Everywhere getting this in the printer menu:
Description:Brother MFC-J6920DW duplex copy Location:coyote.coyote.den Driver:MFC-J6920DW - IPP Everywhere (color, 2-sided printing) Connection:ipp://Brother%20MFC-J6920DW._ipp._tcp.local/ Defaults:job-sheets=none, none media=na_letter_8.5x11in sides=two-sided-long-edge but when I goto the maintenance tab an try to print a test page, cups does not accept me as user and my passwd that works for logins and sudo on a rootless system. All I can do is cancel. This is a VERY OLD problem I've been saddled with since at least wheezy. I assume from the tcp.local above its trying to use the printers net address, not its usb. Both are connected but the net connection is slower than the usb. Or I should say that was on stretch. This is bullseye now. The brother drivers, updated for bullseye are installed but don't work at all well. no duplex and about 15x slower than stretches install. Andy, plz remove your PM when posting to debian-user, firefox makes it very difficult to put the list address as the To: without starting a new, blank msg. It puts the list in the Cc: box and will not copy/paste it to the To: box w/o stripping at the @. Cheers, Gene
