Tektronix Phaser 220e Reference Manual page 155

In the example below, all pen widths are set to 0.35 millimeters. Pen 0 is
white (this is the background pen color), pen 1 is black, pen 2 is red, pen 3 is
green, pen 4 is blue, pen 5 is cyan, pen 6 is magenta, and pen 7 is yellow.
The pen color change is persistent across jobs but not across printer power
cycles; it affects all HP-GL jobs that immediately follow it until the next
printer reset.
Note This Þle affects printer operation. If the printer is shared on a
network, using this Þle may affect the prints requested from other
users.
