Instead, it creates a PostScript file, assuming that you know how to view or print such a file. If you don't have a PostScript previewer, you might want to get the Free Software Foundation's ``Ghostscript`' (or ````gs`''') program, which works very well. On a unix system, you may invoke both Gri and the previewer on the same commandline, e.g., ``gri foo.gri && gs foo.ps`' (many users create a shellscript that does this). Gri PostScript output is standard, and can be viewed with standard viewers such as ``ghostview`' or ``gv`'. ## 4.4: Printing Gri Output Gri output files are in the PostScript page description language. Unix Use a command like ``lpr file.ps`'.
