Spool the current plot to the printer.
Syntax: hardcopy [<filename>] [mono | color]
This command takes whatever is the current display in you plot window, writes it to a postscript file, and then sends it to a printer using the unix lpr command. It will thus be printed on whatever printer lpr uses as your default printer. If a filename is specified, the postscript file will be saved (e.g. “hardcopy dataplot.ps color” will produce a color plot saved in the file dataplot.ps). If mono or color is not given, the hardcopy will be monochrome.
