On my OJ 500 I could successfully print with "cdj550" and "hpdj".
Hpdj uses ghostscript's ordered dithering and does not perform FS dithering in
the driver. This may be worse for pictures, but IMHO better for graphics and
text, because cdj550 uses FS dithering for everything, even for (non-black
color) text, which is IMHO not alway appropriate. It also appears, that hpdj
allows to select the print quality (draft/normal/best) and some other printer
specific features, which cannot be set with the cdj550 driver (mostly I use
hpdj with "draft" setting in the hope to save ink).
For printing pictures (i.e. photos), I think that cdj550's floyd steinberg
dithering is the better choice and results in better LPI resolution.
Also try to play with the various parameters of the drivers (see documentation
in /usr/share/ghostscript/5.50/doc/...)
