^PO
Print Orientation
Description 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.
Format ^POa
This table identifies the parameters for this format:
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.
