About the Printer’s Communication Modes
The following sections explain the communication mode choices
you have with your printer, including the resident emulations,
Simultaneous Interface Operation (SIO), and Emulation Sensing
Processor (ESP) technology. All of these features enhance the
printer-computer interface.
Simultaneous Interface Operation (SIO)
Simultaneous Interface Operation (SIO), a standard feature of
Crown technology, enables your printer to communicate
simultaneously with hosts through the LocalTalk, parallel, serial,
and optional network interface ports. In other words, SIO allows
you to have more than one host communicating with the printer at
one time.
Emulation Sensing Processing (ESP) Modes
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
(for example, PostScript only, HP PCL 5 only, or HP-GL 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 and serial interfaces, and
in the Administration/Emulations menu, you can configure the
printer defaults for each emulation mode. (The LocalTalk interface
uses only PostScript.)
Advanced users can also use PostScript operators to reconfigure
printer ports. The QMS Crown Technical Reference, shipped with
your printer, contains information about PostScript operators.
