If you find out a good "tuning" of this Transfer numbers, I'd be
interested in hacking the Uniprint driver I use at work (on Windblows)
to print eps/ps files to an EPSON 1520.  The images come out sharp, but
the colors are definitely off (it also hedges towards being too light
for many of the colors and dark reds, etc. get too much black.).
(Luckily I have access to a color laserjet with a built-in postscript
driver -- makes it easy!).
