Start Format

Description The ^XA command is used at the beginning of ZPL II code. It is the opening
bracket and indicates the start of a new label format. This command is substituted with a single
ASCII control character STX (control-B, hexadecimal 02).
Format ^XA
Comments Valid ZPL II format requires that label formats should start with the ^XA
command and end with the ^XZ command.
^FOField Origin
Description The ^FO command sets a field origin, relative to the label home (^LH)
position. ^FO sets the upper-left corner of the field area by defining points along the x-axis
and y-axis independent of the rotation.
Format ^FOx,y,z
Comments If the value entered for the x or y parameter is too high, it could position the
field origin completely off the label.
ParametersDetails
x = x-axis location (in
dots)
Accepted Values: 0 to 32000
Default Value: 0
y = y-axis location (in
dots)
Accepted Values: 0 to 32000
Default Value: 0
z = justification
The z parameter is only
supported in firmware
versions V60.14.x,
V50.14.x, or later.
Accepted Values:
0 = left justification
1 = right justification
2 = auto justification (script dependent)
Default Value: lastaccepted ^FW value or ^FW default
This command interacts with the field direction parameter of ^FP and with the rotation
parameter of ^A. For output and examples, see Field Interactions on page 977.
The auto justification option might cause unexpected results if variable fields or bidirectional
text are used with ^FO. For the best results with bidirectional text and/or variable fields, useeither the left of right justification option.

^FD
Field Data
Description The ^FD command defines the data string for the field. The field data can be
any printable character except those used as command prefixes (^ and ~).
Format ^FDa
Comments The ^ and ~ characters can be printed by changing the prefix characters—see
^CD ~CD on page 145 and ^CT ~CT on page 156. The new prefix characterscannot be
printed.
Characters with codes above 127, or the ^ and ~ characters, can be printed using the ^FH and
^FD commands.
• ^CI13 must be selected to print a backslash (\).
For information on using soft hyphens, see Comments on the ^FB command on page 179.

^FS
Field Separator
Description The ^FS command denotes the end of the field definition. Alternatively, ^FS
command can also beissued as a single ASCII control code SI (Control-O, hexadecimal 0F).
Format ^FS

^BY
Bar Code Field Default
Description The ^BY command is used to change the default values for the module width
(in dots), the wide bar to narrow bar width ratio and the bar code height (in dots). It can be
used as often as necessary within a label format.
Format ^BYw,r,h
For parameter r, the actual ratiogenerated is a function of the number of dots in parameter w,
module width. See Table 11 on page 141.
Parameters Details
w = module width (in
dots)
Accepted Values: 1 to 10
Initial Value at power-up: 2
r = wide bar to narrow
bar width ratio
Accepted Values: 2.0 to 3.0, in 0.1 increments
This parameter has no effect on fixed-ratio bar codes.
Default Value: 3.0
h = bar code height (indots)
Initial Value at power-up: 10
Example • Set module width (w) to 9 and the ratio (r) to 2.4. The width of the narrow bar is
9 dots wide and the wide bar is 9 by 2.4, or 21.6 dots. However, since the printer rounds out
to the nearest dot, the wide bar is actually printed at 22 dots.
This produces a bar code with a ratio of 2.44 (22 divided by 9). This ratio is as close to 2.4 as
possible,since only full dots are printed.

^BC
Code 128 Bar Code (Subsets A, B, and C)
Description The ^BC command creates the Code 128 bar code, a high-density, variable
length, continuous, alphanumeric symbology. It was designed for complexly encoded product
identification.
Code 128 has three subsets of characters. There are 106 encoded printing characters in each
set, and each character can...
