Chapter 2 RFID PPI/ZGL Commands

retries The number of automatic attempts to read data from the tag if previous reads failed. The PPI/ZGL absorbs the number and uses the value on the control panel’s LCD.

motion Set this flag to 1 to read data from the tag without moving the label. The printer may adjust the label position while it reads data from the tag, but this adjustment will reverse before any subsequent normal label movement. Even if this flag is set to 1, other commands (i.e., alpha or barcode) may move the label.

The default is 0.

reserved This is a reserved flag. The PPI/ZGL absorbs this number.
