It depends not so much on TeX as on the driver you use for printing.
Dvips is wonderfully helpful in this respect, and that is one of the
reasons to retain the extra step TeX -> PostScript -> PDF.
Scan, (or photograph with a digital camera) and use GIMP to convert to
Encapsulated PostScript (EPS) files. I suggest photography for any
half-tone in which you can sense the screening, because direct scanning
tends to give you a very precise picture of the screened dots. 300 dots
per inch is all you need for half-tones, but if you want really sharp
black and white line art, you will have to learn some techniques in GIMP
and work from as much as 1200 DPI.
Dvips will allow you precise placement and scaling of the EPS results.
Take a look at the University of California journal Classical Antiquity
if you would like to see some results of dvips placement of EPS files.
Issue 23.1 after page 93 will show (Figures 4 and 6) what the risks of
getting too precise a picture of the half-tone screen are.
