Write Tag

Purpose
Format
72
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 ZGL absorbs
this number.
This command is only executed by the demand for
data from any dynamic field. The ZGL absorbs this
command if there are no demands for the data.
This command programs data into an RFID tag
(embedded in the smart label).

start
Starting block location where data will be
programmed into the RFID tag. The ZGL

value.
retries
The number of automatic attempts to write
data into the tag if previous writes failed.
The ZGL absorbs the number and uses
the value on the control panel's LCD.
motion
Set this flag to 1 to program data into the
tag without moving the label. The printer
may adjust the label position while it writes
data into the tag, but this adjustment will
reverse before any subsequent normal
label movement. Even if this flag is set to
