Field Orientation
The ^FW (Field Orientation) instruction sets the default orientation
for all instruction fields that have an orientation (rotation) parameter.
Fields can be rotated 0, 90, 180, 270 degrees clockwise by using this
instruction.
The ^FW instruction only affects fields that follow it. Once you have
issued a ^FW instruction, the setting is retained until you turn off the
printer or send a new ^FW instruction to the printer.
The format for the ^FW instruction is:
^FWr
where
^FW = Set Field Orientation
r = Rotate Field
N = Normal {I.V.P. = N}
R = Rotated 90 degrees;
I = Inverted (180 degrees);
B = Bottom Up (270 degrees read from bottom up).
NOTE 1: If the ^FW instruction is entered with the ‘r’ parameter
missing, the instruction is ignored.
NOTE 2: ^FW only affects the orientation in instructions where the
rotation parameter has not been specifically set. If an instruction
has a specific rotation parameter, that is the one that is used.
