Dumps the contents of a 'X' screen to a laser printer with either b/w or
color options by simply typing:
IDL> hardcopy, /black
It is recommended to only use HARDCOPY to get hardcopies for images. If you want to get a hardcopy of a line plot, then first change the output device to a PostScript file (idl.ps), re-run the plotting program or plotting commands, and then issue the print command. An example would be:
IDL> set_plot, 'ps'
IDL> .run plot_sot
IDL> set_plot, 'x'
