^RZ
Set RFID Tag Password and Lock Tag
Description Use this command to define a password for a tag during writing.
With Gen 2 tags, you can lock a tag’s memory bank with an access password or define a kill
password that can be used to permanently disable the tag. If you do not set access or kill
passwords for a tag, the tag ignores any read or write commands that try to use these functions.
Format ^RZp,m,l
The following table identifies the parameters for this format.
Important • This command is not supported by all printers or firmware. See Table 13
on page 287 for the list of printers and firmware with which you can use this command.
Note • The printer can set a kill password, but the printer cannot kill a tag.
