data . Terminate the command with EM after the last data field to

box, if any text is present.
O₁...O
+
Bytes O₁ through O are used to offset the bar code from the beginning of the
+
line, left margin, last printed position (without carriage return), or as an offset
between bar code symbols, in multiples of 1/72 inch. For example, use a hex
value of 03 (or decimal value of 3) to start the bar code 3/72 inches from the
left margin. If this same value is used for subsequent O
will have 3/72 inch spacing between the bar codes. (See the examples on the
next page.)
Notes:
v When the last column in the line is reached, all additional data will
be truncated, without an error message.
v The maximum offset that can be specified is 255/72 ( 3.5+) inches.
For larger offset, you must print blanks ahead of the barcode.
data₁...data
+
This portion of the command represents the actual bar code data. To print the
data in a human readable form, the HR byte in the SELECT command must
be set to the "print human readable" option as described under the SELECT
Command Format.
Each bar code type has rules for the data
characters that may be used as start (first) and stop (last) characters. See
"Valid Bar Code Data" on page 177 for valid characters.
