Test Pattern Generator
The Test Pattern Generator contains PostScript commands to start test patterns
for a number of Tektronix color printers. It allows you to test a printer as if it
was receiving a file from a host computer. In most cases, the test patterns are
generated by the printer's image processor and then printed by the print engine.
However, in the case of a Phaser 480 printer, the PostScript commands cause the
printer's image processor to forward a command to the print engine which
generates and prints the test pattern.
Note
The Test Pattern Generator should contain firmware version 1.2 or
later.
