Unit 4: Standard Command Codes
SATO GL4xxe SBPL Programming Reference Page 4-51
BASE REFERENCE POINT
FUNCTION
To establish a new base reference point for the current label. The base reference 
point is the top left corner or “origin” from where all print position commands are 
based. This command may be very helpful when using labels less than four inches 
wide to place images on the printable label surface. It may also be used to move 
images past preprinted fields on a label.
FORMAT
<ESC>A3H-aaaa-Vbbbb
-  = This character is optional. When present, it specifies that The 
horizontal offset is in the negative direction. If it is left out the 
offset direction is positive.
aaaa  = Horizontal Print Offset (-Hmax to +Hmax)
bbbb  = Vertical Print Offset (-Vmax to +Vmax)
Place preceding all images based on the new base reference point.

NOTES
Use of this command will set the printer’s Vertical/Horizontal Offset configuration until 
a new Base Reference Point command is issued or the setting is changed from the 
operator panel.
This command may be used more than once in a print job. 
An alternative to using this command is to make changes to your current Horizontal 
and Vertical Print Position commands. 
Example: If the current base reference point is H=1, V=1 and you wish to move all the 
fields on your label downward vertically by 150 dots. You could either, (1) add the 
Base Reference Point command or, (2) change all the vertical position commands by 
an additional 150 dots.
For a more detailed example of the Base Reference Point command, refer to the 
Introduction unit.
The printer will not “wrap” if any part of a character or image extends beyond the last 
print dot position. It will disappear and not be visible on any part of the label.
