HP 5961-0509 manual DI Command Label Direction, Example Using the DI Command, Directioncr

When using either method, at least one parameter must not be zero. The ratio of one parameter to the other is more important than the actual numbers. The following table lists three common label angles produced by using 1’s and 0’s.

Table 23-13

DI Command	Label Direction
DI 1,0	horizontal
DI 0,1	vertical
DI 1,1 or DI 0.7,0.7	45° angle
(or any parameters equal to each other)

The relative size and sign of the two parameters determine the amount of rotation. If you imagine the current pen location to be the origin of a coordinate system for the label, you can see that the signs of the parameters determine which quadrant the label is in.

Table 23-14 Example: Using the DI Command

ECE	Reset the printer.
EC%0B	Enter HP-GL/2 mode.
IN;	Initialize HP-GL/2 mode.
SP1;	Select pen number 1. Even though there is no
	physical pen, the SP command must be used
	to enable printing.
PA3500,2500;	Enter absolute plotting mode and move to
	(3500,2500).
DT*;	Define (*) as the label terminator.
DI1,1;LB	Print the word “DIRECTION” in the first
DIRECTIONCR*;	quadrant and send a Carriage Return to return
	the pen to the Carriage Return point
	(3500,2500).
DI1,-1;LB	Print the same word in the fourth quadrant and
DIRECTIONCR*;	return the carriage to the Carriage Return
	point.
