Advanced printing options for LBP2900B (toner density)

Hmm - this is what I see:

From the name (LBP2900 vs. LBP2900B) - it’s a slightly different model though.

… on second thought:
no, actually not a different model - the LBP2900B is just the name I gave it during set up.
which I did like this:

sudo lpadmin -p LBP2900B -m CNCUPSLBP2900CAPTK.ppd -v ccp://localhost:59687 -E
sudo ccpdadmin -p LBP2900B -o /dev/usb/lp0

The whole process is documented here:
