1
^XA
Indicates start of label format.
2
^RS8
Sets tag type to Gen 2
3
^FO50,50
^A0N,65
^FN3
^FS
When the label prints, the data read from the tag at
field variable 3 (
^FN3) will be printed at location
50,50.
4
^RFW,H
^FD0102030405
^FS
W,H = write hex
Encodes 12 bytes of data (96 bits) to the tag with
7 bytes of zeroes as padding. The data written is:
010203040500000000000000
5
^FN3
^RFR,H
^FS
R,H = read hexadecimal
Reads the tag data into field variable 3 (
^FN3).
After this occurs, any fields in this label format that
have
^FN3 will be replaced with this read data.
6
^HV3
Returns the value in ^FN3 to the host computer.
Data is sent over whichever communication channel
is established with the host (such as parallel, serial,
USB, Ethernet). In this example,
010203040500000000000000 would be returned to
the host.
