Frank, I added your information because it could be usefull for other people that have the same printer model. According to the link there seems to be a problem in the PostScript driver for your printer. I think you better use any of the PCL based drivers included with ubuntu (e.g. pxlmono) as suggested here: http://lists.freestandards.org/pipermail/printing-user-brother/2006/001205.html Let us know what driver you used and if duplex printing works with it.
Kind regards, Pascal -- unable to print duplex on Brother HL-5150D printer https://launchpad.net/bugs/21306 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
