The communication between the RFID tag and the printer is established
when the transponder lines up with the printer’s antenna.
Note • The transponder position, prior to encode/decode, is critical. The optimal
transponder position varies with antenna coil size and type of RFID IC used. It is
important to use media and tags that have been specifically designed for use in this
printer. Failure to do so may result in the inability to read or program the embedded
RFID tags.
Printing and programming of smart labels is handled through the use of
Zebra's printer programming language, ZPL. The printer segments the
received ZPL's RFID-specific and printing-related commands. The printer
will execute the RFID commands first, followed by those for printing
barcodes and text. Each transponder has blocks of addressable memory that
are written to and read from through ZPL commands. Many transponders
also contain a pre-programmed unique ID/serial number. The ZPL
commands also provide for exception handling, such as setting the number
of read/write retries before declaring the transponder defective.
