I would like to print copies of line plots that use different
colors for different lines, but on a non-PS printer. I have
an HP Deskjet 870Cse (fairly nice inkjet color printer). I've tried
using the PCL device type when running from Windows, and then
doing
spawn,'copy plotfile.pcl LPT1:'
but this is EXTREMELY slow - several minutes for a very simple
plot - and it blocks IDL from doing anything else until the plot
is done.
As an alternative, I have saved color line plots in PS mode,
and then used GhostView to view the file. So far so good, but
when I then use the 'print to non-PS printer' option, it comes
out in black and gray instead of in color.
I suspect I am not the only one who wants to do this - suggestions
eagerly awaited!

When you select /color with device also select bits_per_pixel=8, this will
prevent the coarse rasterization, I had the same problem as well as being
unable to viualize all the colors in my image plots. Your method to import
into another program and converting it for printing is probably best. I
create arrays of figures by reading them into CorelDraw.
