I have a HP PSC 1210 (all in one job) but am having trouble with
printing. The problem is not to get it working as it does print and I
use it daily but the problem is that it doesn't do it intelligently.
This printer has two cartridges (colour and black) but if I tell
Ubuntu it is a colour printer it prints everything, including black
from the colour cartridge so the colour runs out before the black has
even been used if I don't just use the black cartridge for printing
text pages.

Does anyone here know how I can fix this so I can leave it on one
single setting and not have to change it manually but that the
computer will use both cartridges as required?
