Technical information

All your printer’s ports are active at the same time, so you can attach
serial, parallel, Ethernet, and optional interface cables and communi-
cate to all ports from four host computers or networks simultaneously.
You can either allow your printer to operate in its default ESP mode or
configure its ports to accept jobs in only a particular emulation mode
(for example, PostScript emulation only, HP PCL only, or HP-GL emu-
lation only). The default printer communication settings can be
changed through the Configuration menu, which you access through
the control panel—in the Administration/Communications menu, you
can choose a default emulation for the parallel, serial, and Ethernet
interfaces, and in the Administration/Emulations menu, you can con-
figure the printer defaults for each emulation mode. (The optional
LocalTalk interface uses only PostScript.)
Advanced users can also use PostScript operators to reconfigure
printer ports. The
QMS Crown Technical Reference contains informa-
tion about PostScript operators. Generally, it is best to keep your
printer in ESP mode. Since ESP mode is the factory default, all you
have to do to use it initially is connect your host and printer and then
send a file.
Gamma Correction is the compression or expansion of the ranges of
dark or light shades in a printed image to provide the best copy of
scanned images.
