Chapter 2 RFID PPI/ZGL Commands
56
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.
Comments
This command is only executed by the demand for
data from any dynamic field. The PPI/ZGL absorbs this
command if there are no demands for the data.
Write Tag
Purpose This command programs data into an RFID tag
(embedded in the smart label).

write data into the tag if previous writes
failed. The PPI/ZGL absorbs the number
