Introduction
This chapter provides additional technical information on ESP and
SIO features, gamma correction, memory management, end job
mode, parallel interface modes, the PS Protocol option, and HP-GL
color-to-grayscale conversion.
The Emulation Sensing
Processor (ESP)
The 1725E Print System employs ESP technology, which works with
most popular commercially available applications, and uses a form of
artificial intelligence to analyze incoming file data and select the
appropriate printer emulation from those installed on the printer. Your
printer can interpret printer languages without your having to change
printer switch settings or send software commands to accommodate
different printer languages.
When your printer is in ESP mode, you can easily print files prepared
for a PostScript printer or an HP LaserJet. The file prints correctly as
long as it begins with the traditional PostScript or HP PCL commands
for such items as page formats and job parameters (number of cop-
ies, page margins, fonts).
The QMS 1725E Print System prints almost any file sent in an emula-
tion ESP technology understands, whether you have one, two, or
more hosts, and whether you are communicating through a parallel,
serial, Ethernet or optional LocalTalk interface. Most users never
have to change from ESP mode to another mode.
