Active Emulation - Printronix T2N series User Manual

Auto Selection Media Type
Manual calibrate does not work with "Auto Selection". This Media Type is only valid for Auto
Calibration. If the user clicks the "Manual Setup" button with "Auto Selection" as the Media Type, an
error message "Can't Calibrate" displays.

Active Emulation

Active Emulation controls how data is processed in the T2N printer. The printer contains three
parsers: PGL, ZGL, and EGL. When the Printer Function button is pressed, the "Emulation Setup"
window opens. With default setting "Auto Switch", all three emulations are active. The data is
analyzed in ZGL, PGL, and EGL, respectively, as shown in Figure 25, page 97.
When an emulation examines the data, it will execute recognized commands and print forms based
on the host application. Any data not recognized as part of a form or otherwise legitimate command,
is passed to the next emulation for examination. If none of the emulations recognize the data, it will
be ignored.
By choosing an emulation in the "Emulation Setup" window and clicking the "Set" button, that
emulation will be the only Active Emulation to examine the data. The data will either be processed or
ignored. The following are situations in which the Active Emulation should be set to a specific
emulation:

It is possible that two different emulations would have overlapping commands. Setting a
specific emulation forces the data to be analyzed solely by that emulation.

It takes more time for data to be analyzed serially by three emulations. For example, if the
host applications are exclusively in EGL, data analysis is faster when the Active Emulation is
set to "EGL".

PGL is the only emulation capable of printing straight text. If a job included text outside of a
form, setting the Active Emulation allows PGL to print the data as text. Control of how that
text is processed can be specified via the PGL tab along with Advanced Settings "PGL Text
Printing".
If the user does not want to change the existing setting, close the "Emulation Setup" window and no
change will take effect.
