What I do is this:

setplot,'ps'
device,/color,bits=8 ;...and whatever other DEVICE options you want

tvclt,19
tv,blahblah
oplot,blahbhla ;Basically do whatever I did to get it to appear
;in my TV window in the first place. One hint:
;Do everything in normalized or data coordinates...
;device coordinates are strange for PostScript.

device,/close
$lpr -Pcolorprinter idl.ps

You'll get much better-looking output than you would do otherwise. I also
often use true-color images (i.e. 3-plane RGB images) when I'm combining
images into one, so I'm not limited to one color table.
