Other Optional Emulations
If you have an optional emulation installed, such as LN03 Plus, see
the documentation that came with it for a description of the options
under the Administration/ Emulations menu. The QMS Crown
Technical Reference and QMS Document Option Commands
(optional manuals available from your QMS vendor) also have
information on optional emulations.
Administration/Emulations/ESP Default
This setting tells the printer what emulation to default to if the
printer’s emulation sensing technology is unable to identify the
emulation needed for a particular job. Default emulation options
include PostScript, PCL 5C, HP-GL, and Lineprinter. Optional
emulations, such as LN03 Plus, appear only if installed. The factory
default emulation for ESP is PCL 5C. Any change to this option
takes effect only after turning the printer off and on again.
