## Printing on UNIX Machines

On UNIX machines Understand for C++ uses Postscript as its primary output format. The output files created are Level 2, Encapsulated Postscript without a preview image.

All output is to a file, the file can optionally be sent to a queuing command (such as lp or lpr).

Initially the Print Dialog appears:

- Print Range specify optional range of pages (if more than one page)
- Copies - specify number of copies of each printed page
- Print to File, if checked then a dialog is displayed so you can specify what file to print to.
- Setup - use to further configure printing, as shown in this panel:

- Printer Command - Sets the system command used to print. The default is lpr. This command name may be set to any command. No checking is made to ensure it is a valid command or that it is on your executable search path. The name of the Postscript file is passed as its first argument. The text (if any) contained in the Printer Options field is passed as arguments following the Postscript file name.
- Paper Types Toggle - Lets you choose what paper size to use. The default is 8 1/2 by 11 (letter).
