^PO

^PO

The
^PO
 command inverts the label format 180 degrees. The label appears to be printed upside down. If the original label contains commands such as
^LL
,
^LS
,
^LT
 and
^PF
, the inverted label output is affected differently.

Print Orientation

Format:
^POa
Parameters
Details
a =
 invert the label 180 degrees
Values:
N =
 normal 
I =
 invert
Default:
N
Example
This is an example of printing a label at 180 degrees:
The
^POI
 command inverts the x,y coordinates. All image placement is relative to these inverted coordinates. Therefore, a different
^LH
 (Label Home) can be used to move the print back onto the label.
Comments:
 If multiple
^PO
 commands are issued in the same label format; only the last command sent to the printer is used.
Once the
^PO
 command is sent, the setting is retained until another
^PO
 command is received, or the printer is turned off.
The
N
 value for the
a
 parameter is not supported on the HC100™ printer.
