represent the physical characteristics of the printer models. This command is
used in conjunction with the Finish Mode feature; see the D27 command bit
position 8 for more information.

X 165 Set the Reflective Dot2Gap Value:
This is the distance of the reflective sensor, which detects blackline
registration marks, to the dot row. This distance is set at the factory and is
typically not needed to be changed. The reflective Dot2gap distances
represent the physical characteristics of the printer models.

5.4.7 Auto-size Commands
The auto-size command attempts to automatically calculate important format values for the
label header including LSY, GAP, AGD, SPG, ^D90, and the ^D91 values. The printer
feeds a sample of labels through the GAP sensors and takes an average of the values it
receives. The auto-size command uses the appropriate sensors to detect the registration
marks set by the ^D47 command. Before issuing the auto-size command, verify that the
^D47 is set to the proper setting for the media being used.
When using media that contains a blackline for the registration mark, first execute the
^A1^D47 command sequence before issuing the auto-size command or the results
may be invalid.
