An HPG graphics file can be output for any image displayed on the client areas of the system. To output a graphics file select Hardcopy from the menu bar. You may also produce a Postscript graphics file or copy an image to the clipboard.

HPG (Hewlett Packard Graphics Language - HPGL) is vector/text format which can be copied directly to a HPGL compliant printer or embedded in a word processor. Because the format is vector the image can be resized (and stretched) without any undesirable distortion of the image data.

The Internet is a good source of information on the HPGL language. Hewlett Packard also produce a book, The HP-GL/2 and HP RTL Reference Guide - A Handbook for developers - ISBN: 0-201-63325-6, which is a generic guide to the language.
