Postscript Printer with duplexer
I've got a postscript-printer with an automatic duplexer (Brother HL 1650). The distribution is Suse 7.2. The printer is run as an generic postscript level 2 printer.
Everything works fine -except for the duplexer, which is ignored.
Any idea how to tell the system, that the printer shoul use the duplexer?
