Advantages; Implementation; Hp-Gl Color Encoding - QMS 1725E Reference

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 for-
mat 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 avail-
able information on device drivers or binary filter programs.

HP-GL Color Encoding

The term "pen" in the HP-GL emulation refers to a logical pen (in
other words, the current pen position) rather than to 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 1725E Print System is a monochrome (black and
white) printer, the pen colors are converted to shades of gray. The
default color mappings for the 8 pens are as follows:
Pen
1
2
3
4
5
6
7
8
