Printer Interface

The printer interface is the point where the data (signal) cable from the host
computer plugs into the printer. The printer interface processes all signals and
data to and from the host computer.
The printer supports a number of standard and optional interfaces to the host:
computer:
•
•
•
•
•
•
Selection of the interface is controlled by configuration menus accessed at the
control panel. It is possible to physically connect more than one interface, but
only one interface may be electrically active at any given time.
Graphics
The VGL Advanced Graphics programming language (a QMS graphics
emulation) and the PGL Advanced Graphics programming language (a
Printronix IGP emulation) are options that install in flash memory on the
controller board.
These programming languages simplify the job of creating forms, bar codes,
logos, expanded characters, and other graphics. The languages enable the
printer to print sideways, upside down, and to make forms combining
graphics, alphanumeric data, and bar codes—all in a single pass. Documents
explaining configuration, operation, and programming are included with each
option.
