Parameter Values
The Printronix S828 Printer allows flexibility in selecting various options to perform a wide range of functions.
Parameter values are initially set at the factory. The printer uses these values to format the page and to
control forms movement. The parameter values also allow the operator to select the printer address,
language, and print mode and compatibility options, and to turn the alarm on or off.
The printer can use the initial factory set values, or the operator can change these values. Any new value
selection made at the operator panel becomes the new parameter value immediately upon selection. If this
configuration is saved by the operator into the power-on custom set, this value remains as the new
parameter value, even after the printer power switch is turned Off (O).
The operator can select the following parameter values at the operator panel and change them:
● Characters per inch (CPI)
● Lines per inch (LPI)
● Maximum print position (MPP)
● Maximum page length (MPL) (See Note)
● Language
● Print quality
● Alarm (Enabled/Disabled)
● Graphics and Bar Code mode
● Left margin
● Emulation mode
Note: An MPL setting that results in a page length less than 762 mm (3 in.) causes a throughput
reduction. A maximum reduction of about 50 percent occurs at an MPL setting of one line per page.
The application program can override any of the parameter values, except for turning the alarm on or off
changing the address selection, changing the emulation determines what parameter value the printer uses:
1. The printer uses the program specified value.
2. If no program command has specified the value, the printer uses the current parameter value.
