wise be created using all three CMYK colours.

Gloss Variance Mainly duplex - especially at very low usage rates.
GND Ground
GPD Minidrivers A Generic Printer Description file has a function similar to PPD files. This
format was developed by Microsoft to provide a simple method to
develop drivers for non-postScript printers. Standard GPD mini drivers
share the same lamentations as the PPD mini drivers, but they too can
be enhanced using plug-ins. GPD Mini drivers are a new technology
introduced for Windows 2000 and they will also be supported Windows
NT 4. In Windows 95/98, a similar, but less powerful 'unidriver' format
was used.
