1 ^XA Indicates start of label format.
2 ^RS3 Sets tag type to EPC Class 1 64-bit.
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
Writes 8 bytes of data (64 bits) to the tag with 3 bytes
of zeroes as padding. The data written is:
0102030405000000
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 Return 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, 0102030405000000
would be returned to the host.
7 ^XZ Indicates end of label format.
