r - Set Relative Reference Point
Purpose: This command is used to move the reference point for the x-axis
and y-axis relative to the label width set by a previous q
command.
Syntax: rp
1
,p
2
.
Remarks: The relative reference point command is used to establish the top
and left margins relative to the label width. For narrow labels, the
r command can be used after a q command, which has the
benefit of making better use of a limited image buffer. The values
for the latest r command (or R, whichever was last executed) are
printed on the test label.
The print direction commands ZB and ZT affect the location of
the relative reference point as illustrated.
