The Phaser 6510 is on the home lan ethernet connected. My desktop system is bare-bones, icewm and no DE, running FreeBSD 14.0. The printer is found with the CUPS browser (Firefox) interface, but a ppd or driver for other than Windows or Mac is not available from Xerox and not found in the gutenprint list. I've tried various ppd including generics. Also connected as ipp and tried ipp-everywhere. With all tries I can set defaults from the CUPS web administraion menu, but most of these settings don't get set. Specifically, paper source and pages to print set in print dialogs raised in xpdf, LibreOffice or jedit have no effect; print jobs are always whole document from tray 1. My understanding of the issue is small, but I suspect there is no solution and I'll have to keep printing from an old Mac mini otherwise not used anymore as my FreeBSD desktop computer is all I need. But I hope I can put the Mac mini away and reclaim some desk space. Thanks for any advice.
