[Gimp-print-devel] Epson 740

[Frank v. M. <F.v...@in...>]

I'm trying gimp 1.0.4 + print-3.1.3 on a RedHat 6.1 box for
this printer. This doesn't look good. I have tried various
settings in the file->print menu but at best the color dithering
was much worse than with ghostscript: I tried versions 5.10 and 6.01, both
with .upp files for the Epson 740 which I got from another place.

And even the uniprint driver in ghostscript dithers less good
than the Epson supplied Windows drivers (a friend tried it for
me because I don't have Windows9~).

After experimenting a while I noticed that the print output
of gimp is not reproducable: as if something is really going wrong.
Suddenly the white background turned into black (lots of ink...).
When the same picture is printed to a file multiple times the
output tends to shrink in size:

After restarting gimp:
