ZPL II Commands for RFID
Printing and encoding (writing) of “smart” labels is handled through the use of Zebra
Programming Language (ZPL). Each transponder has memory that can be read from through
ZPL commands, and most transponders have memory that can be written to. The print engine
divides the ZPL commands that it receives into two categories: RFID and non-RFID (such as
the printing commands for bar codes or human-readable text).
Programming Language (ZPL). Each transponder has memory that can be read from through
ZPL commands, and most transponders have memory that can be written to. The print engine
divides the ZPL commands that it receives into two categories: RFID and non-RFID (such as
the printing commands for bar codes or human-readable text).
ZPL commands also provide for exception handling, such as setting the number of read/write
retries before declaring a transponder defective. For example, if an RFID transponder fails to
program correctly or cannot be detected, the print engine ejects it and prints the word “VOID”
across the label. This process continues for the number of RFID tags specified by the
retries before declaring a transponder defective. For example, if an RFID transponder fails to
program correctly or cannot be detected, the print engine ejects it and prints the word “VOID”
across the label. This process continues for the number of RFID tags specified by the
^RS
command using the same data and format.
The following pages provide the ZPL II commands that can be used for RFID applications.
