R – Set Reference Point
Description This command is used to move the reference point for the X-
and Y-axes. All horizontal and vertical measurements in other
commands use the setting for R as the origin for measurements.
Syntax
Rp

Parameters p
1
Horizontal (left) margin measured in dots (default 000).
p
2
Vertical (top) margin measured in dots (default 000).
Remarks
The reference point command is used to establish top and left
margins to prevent printing off the edge of the label. A minimum
margin of 1 mm should be used on all sides of the label.
Repeated printing outside the edge of the media can cause
excessive printhead wear.
For narrow labels, the R command could be substituted by a
q command, which has the benefi t of making better use of a
limited image buffer. However, the q command cannot affect the
vertical margin. Any R command after a q command will revoke
the latter.
The print direction commands ZB and ZT affect the location of
the reference point, as illustrated below:
Example

:

and a 100 dot top margin.
