HP-GL/2 & PCL Orientation Interactions

The relationship between the orientation of the HP-GL/2 coordinate system and the PCL coordinate system is important. Figure 17-6 illustrates this relationship for the default HP-GL/2 orientation (RO 0) and the PCL logical page orientation. As shown in the illustration, in the default HP-GL/2 orientation, the origin of the HP-GL/2 coordinate system defaults to the lower-left corner of the PCL Picture Frame. (HP-GL/2 and PCL X-coordinates increase in the same direction, but the Y-coordinates increase in opposite directions.) Notice that a change in the PCL logical page orientation changes the orientation of the PCL coordinate system and the HP-GL/2 coordinate system.

	The relationship between the coordinate systems can be changed
	using the HP-GL/2 Rotate (RO) command. Rotations specified by the
	RO command are relative to the default HP-GL/2 orientation (which
	matches the PCL orientation). Figure 17-7 shows how the RO
	command modifies the default HP-GL/2 orientation.
Note	A change in PCL print direction has no effect on the HP-GL/2
	orientation, the physical position of the picture frame, or the picture
	frame anchor point.
