The next five lines are layout and configuration for each data field in the format.
The command ^D56 selects the user’s layout or more simply the end of the formatting
information.
The command ^D2 instructs the printer to start accepting data for each of the defined
field’s strings that are entered into the previous format received (between the ^D57 and
^D56 commands). Field #1 defines the placement and configuration for Text Data String
#1; Field #2 defines the placement and configuration for Text Data String #2, etc… The
label is printed from the bottom left corner to the top of the label.
The next three lines are the text data for the associated field format lines.
Text Data String #4 is being accessed twice. The format places the Text “012345” on the
label and then is accessed again placing a Code39 symbol representing “012345” on the
label.
The command ^D3 instructs the printer to print.

4.4 Label Header
The label header consists of eleven parameters that control the media layout as well as
printer configuration. A comma (,) delimiter is used to separate the parameters and a
carriage return is required to terminate the header.
The values for header elements requiring measurements are expressed as thermal dots or
pixels. Dot or pixel size varies depending upon the print resolution of the print head. Two
print resolutions are currently available for the 224 and 424 printers (203 DPI and 300 DPI).
The dot size of a 203 dots per inch head (8 dots/mm) is 0.0049”. The dot size of a 300 dots
per inch head (12 dots/mm) is 0.0032”. The dot size is the same in both the horizontal and
vertical direction. For example, a 4” X 6” label printed with a 203 DPI print head would be
