My experience is that you probably need to fiddle with gamma,
brightness, and even the dots-per-inch settings to get acceptable
results (e.g. 1440sw may put too much ink on the paper). I never did
find a way of relating the available paper types in the driver to the
papers I can buy (e.g. three or four different qualities of glossy A4
photo paper for *each* of the big name brands). You'll probably need to
standardise on certain paper types, at least at first, and you're going
to waste a lot of ink and become sick of the sight of your test
pictures. Last time I printed any photos, I was using kodak picture
paper (about one step above basic inkjet paper) for tests (e.g.
size/position), but it tells you *nothing* about the results you'll get
on the sort of media you could frame.

When you talk about calibrating, I think your aims may be very high
quality - I've long since settled for adequate quality on the pictures
I print myself, there are more than enough other problems (like getting
borderless prints). So far I haven't seen any calibration software that
runs on linux.
