ZPL II Commands for RFID

ZPL II Commands for RFID

This section contains the ZPL commands for RFID-specific applications. For non-RFID ZPL commands, refer to the ZPL II Programming Guide (part number 46530L). A copy is available on the R110Xi/R170Xi User CD (part number 23062-003) and online at http://www.zebra.com/manuals.

In addition to reading or encoding RFID tags, these ZPL commands also provide for RFID exception handling, such as setting the number of read/write retries before declaring a transponder defective (set with ^RT and ^WT) or setting the number of labels that will be attempted if an error occurs (set with ^RS).

For example, if an RFID label fails to program correctly or if the transponder cannot be detected, the printer ejects the label and prints VOID across it. The printer will try to print another label with the same data and format for the number of RFID labels specified by the ^RS command. If the problem persists, the printer follows the error handling instructions specified by the ^RS command: the printer may remove the problematic format from the print queue and proceed with the next format (if one exists in the buffer), or it may place the printer in Pause or Error mode.

Important • If a parameter in the following tables is designated as not applicable, any value entered for the parameter will be ignored, but the place holder for the field is required.
