No question this is the preferred solution, but the
problem I had was with a PrintWindow program that does
a quick screen dump and sends it to a printer. I solved
the problem by just doing a Color_Quan on the 24-bit
image and loaded the color tables before I Set_Plot
to PRINTER. Works OK, but that PRINTER device is more
trouble than it is worth, once again. :-(
Cheers,
David

This is something of a dodge around the problem, but
writing a postscript file and then spawning "lp filename"
should do the trick. I don't think I've ever encountered
a modern Linux box whose printer driver didn't speak Postscript.

Oh, if I started down that path, there would be no end
of it. :-(

P.S. It was a 24-bit image I was trying to print.
A screen dump from a 24-bit display. TV, image, true=1.
I'll try an 8-bit image, but that's like stepping
back to the 1970's, isn't it?

What type of image? Some 3-channel RGB I am guessing? That might be
the problem. Have you tried a bitmap, or an {E}PS?

It sounds like the destination doesn't take RGB data, only indexed
files. But I haven't dealt with this exact message myself.
-k.
P.S. Who are you, and what have you done with David Fanning? I
thought you didn't do low-level Linux :) Next, are you going to be
writing in with emacs IDLWAVE questions?
