RO, Rotate Coordinate System
This command rotates the printer’s coordinate system relative to the
default HP-GL/2 coordinate system, in the following increments of
rotation: 90°, 180°, and 270°. Use RO to orient your drawing vertically
or horizontally, or to reverse the orientation.

The printer interprets the command parameters as follows:
z
No Parameter — Defaults the orientation of the coordinate
system to 0°. Equivalent to
(RO0)
. This is the same as PCL’s
current orientation.
z
Angle — Specifies the degree of rotation:
0 Sets the orientation to PCL’s current orientation.
90 Rotates and shifts the coordinate system 90 degrees in a
positive angle of rotation from PCL’s current orientation.
180 Rotates and shifts the coordinate system 180 degrees in a
positive angle of rotation from PCL’s current orientation.
270 Rotates and shifts the coordinate system 270 degrees in a
positive angle of rotation from PCL’s current orientation.
Angle of Rotation
Note A
positive angle
of rotation is in the direction of the +X-axis to the
+Y-axis as shown below. (A
negative angle
of rotation is not allowed in
the RO command.)
