Start a new IDL session and type:
device, true_color=24
window, /free
device, decomposed=0, retain=2
These commands sould be loaded in an IDL startup file (e.g.
$HOME/idl_startup.pro). Set IDL_STARTUP to point to the startup file,
e.g
setenv IDL_STARTUP $HOME/idl_startup.pro

By printed, you mean the Postscript or Printer devices? A utility that
may help is my IMDISP image display program:
http://cimss.ssec.wisc.edu/~gumley/imdisp.html
Then you could try this:
demo_getdata, image, file='hurric.dat'
loadct, 13
imdisp, image
set_plot, 'PRINTER'
loadct, 13
imdisp, image
Cheers,
Liam.
