OK, I think I see where the problem could be with this bug. With older CUPS, CONTENT_TYPE is "application/vnd.cups-raw", and with newer it's "application/vnd.cups-postscript".
CUPS 1.2.2 is doing coversion on client side, which it shouldn't. -- Can't print with cupsys1.2.2-0ubuntu0.6.06 https://launchpad.net/bugs/57083 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
