Advantages
The main advantage of using the Binary and Fixed Binary PS
protocol modes when sending binary data is that these modes
compress the data stream allowing your documents to be smaller
so you can send smaller jobs to the printer. For example, some
device drivers can format bit map images as binary data instead of
as ASCII hex data.
Implementation
To implement PS protocol for sending binary data on your system
you need a device driver available with some applications or
operating systems, or you can alternatively use a program to read
the data and write out the quoted characters. See your QMS vendor
for any available information on device drivers or binary filter
programs.
HP-GL Emulation Color Encoding Equation
The term “pen” in the HP-GL emulation refers to a logical pen (i.e.,
the current pen position) rather than a physical pen on a plotter. A
pen and a pen color are selected to draw images. This emulation
supports 8 pens and pen colors. Since your QMS 860 Print System
is a monochrome (black and white) printer, the pen colors are
converted to shades of gray. The color mappings for the 8 pens are
as follows:
Pen Pen Color Level of Gray
1 Black 100%
2 Black 100%
3 Red 70%
4 Green 41%
5 Blue 89%
