I don't know the details of HP's technology, but the results from
the HP2000C, which uses the PhotoRET technique, looks fully acceptable,
although you would not confuse the results with actual photographic
prints. HP have licensed some techniques from Kodak, who ought to know
how to make pictures. Printing on "photo quality" paper, the pictures
look a little grainy, especially i gray areas. From 50 cm distance
the graininess is barely noticeable.
All in all quite neat quality for an office ink jet printer. It is
in even fast enough to rival my old LaserJet II when printing B&W.
Oly contents: I'm waiting (im)patiently for the UKP199,- Olympus ES10
scanner I ordered a couple of weeks ago. It should give some good
material to test the printer with.
