Vector Graphics; Gl/2 Commands And Syntax - Star Micronics 4111 Applications Manual

The Star LaserPrinter 4111 provides the ability to print vector graphics using
the GL/2 graphics language.
Printing with GL/2 requires leaving the PCL mode and entering the GL/2
mode. Switching between modes involves only a few commands and
software applications may easily switch between the two modes as needed
— without affecting performance.

The GL/2 commands have four
separator(s), and a terminator.

components: a mnemonic, parameter(s),
Mnemonic — The two-letter mnemonic is designed to remind you of the
command's function. The mnemonic cab be uppercase or lowercase.
Parameter(s) — Some commands have no parameters; for those com-
mands having them, parameters can be either required or optional.
Optional parameters are enclosed in brackets [ ].
Separator(s) — When you use parameters, you must separate them with
a comma or space, or in the case of a numeric parameter, with a + or – sign.
(Commas are recommended because some computers eliminate spaces,
especially when sending variables.)
Terminator — All commands require a terminator. GL/2 commands are
terminated by a semicolon or the first letter of the next mnemonic. The last
command prior to exiting GL/2 mode must be terminated with a semico-
lon.
