The Configuration Main Menu
Active Versus Saved Configurations
When you change a parameter value, it is active as long as the printer is on or
until it is changed again. This is true whether you use the operator panel or
send a control code from the host. Parameter values defined by control codes
override the active operator panel parameters when the printer is using any of
the parallel or serial interfaces. For example, if you set the line spacing to 6 lpi
with the operator panel, and application software later changes this to 8 lpi
with a control code, the control code setting overrides the operator panel
setting.
Using the operator panel, you can save the parameters as a customized
configuration that is stored in non-volatile random access memory (NVRAM).
A saved configuration is not lost when you power off the printer.
NOTE: Saved configurations are also referred to as “custom sets.”
There are no control codes that allow you to save a parameter in NVRAM.
However, you can save a configuration defined partially by control codes and
store it in NVRAM using the operator panel. You can also save configuration
values using PTR_SETUP. See page 100.
The Configuration Main Menu
Figure 54 shows an overview of the printer configuration menus. The pages
that follow describe how to enter program mode, print the current
configuration, change configuration parameters, and save and load custom
sets.
For specific configuration menu options and their descriptions, refer to
Chapter 4, “Configuration Menus.”
NOTE: The menus that are displayed from the operator panel are determined
by the installed features.
Each feature is shipped with a document that describes the feature in
detail. For more information about these documents, see the “Related
Documents” section that begins on page 12.
