//Read Tag into data element 1, 8–byte (16 characters)
//long (hex format).
//Print data in element 1.
//End and print label.
Same as Example 1, except an alternative ZGL syntax
that does not require underscores between the hex
characters is used.
//Begin ZPL form.
//Write Tag with data = "87D0034567ABCDEF"
//(hex format).
//Read Tag into data element 1, 8–byte (16 characters)
//long (hex format).

//End and print label.

the tag.
//Begin ZPL form.

//Print tag data in FN1.
//Read tag data and store into FN1.
//End and print label.
