Configuring printers (cups)

[Magnus Therning]

In my attempts to slowly migrate over to using only Linux at work I am
now at printing.

Pointing nmap at the printer revealed that it listens on the ipp port.
Using the administrative tool for printers I added the address:

 ipp://10.70.224.34/

Voila, I can print. I repeated the procedure for a few other,
specialised printers. It all works nicely.

However, all printers are capable of duplex printing and I only got
simplex :( I tried configuring through the same tool (properties for
each printer) but my changes don't seem to stick. I also tried pointing
my browser to localhost:631 to see if I could get any further using
CUPS' own configuration, but there I got stuck at a password request
(password for for "CUPS" user, who is that?).

Any pointers?
