It seems like the PRINTER device allows decomposed 24-bit colors to be used.
The following example produces a blue on white plot in IDL 5.3 on my
Windows98 PC. When dialog_printersetup is called, I select the 'HP Color
Laserjet PS' printer, with output directed to a file.
result = dialog_printersetup()
plot, indgen(10), color='FF0000'XL
Something similar could be probably be configured in IDL for UNIX. Let me
know how it goes.
