ZPL II Commands for RFID

^HR

Calibrate RFID Transponder Position

Description Use this command to initiate an RFID transponder calibration for a specific

RFID label. Results are returned to the host computer. This calibration is used to determine the

optimal programming position for RFID media that may not meet the transponder placement

specifications for the printer.

During transponder calibration, the printer feeds the RFID label one millimeter at a time while

taking readings (via the READ TAG command and the WRITE TAG commands) to profile the

RFID transponder. Based on the results, the printer determines the optimal programming

position for the label and returns a results table to the host. The calibrated value is used as the

programming position for the ^RS command, can be overwritten by the ^RS command, and is

saved to nonvolatile memory (the value is saved even if the power is turned off).

This calibration takes into account the print mode, backfeed mode, and tear off position. The

RUN option in the RFID TAG CALIB control panel parameter performs the same

calibration but does not create a results table.

Format ^HRa,b

This table identifies the parameters for this format.

Important • Consider the following before using this command:

•This command is not supported by all printers or firmware. See Printer and Firmware

Compatibility onpage 82 for the list of printers and firmware with which you can use this

command.

•Do not perform transponder calibration for RFID media that meets the transponder

placement specifications for your printer. Doing so will slow the printer’s throughput

unnecessarily. To order media that is designed for use with your RFID printer, contact

your authorized Zebra reseller.

Important • If a label format specifies a value for parameter p (read/write position of the

transponder) in the ^RS command, that value will be used for the programming position for

all RFID labels until a new position is specified or until the printer is turned Off (O) and then

back On (I).

Parameters Details

a= start string User text to appear before the results table.

Accepted values: any string less than 65 characters

Default value: start

b=end string User text to appear after the results table.

Accepted values: any string less than 65 characters

Default value: end
