^WT
Write Tag
Description This command allows you to program the current RFID tag.
Format
^WTb,r,m,w,f,v
The following table identifies the parameters for this format.
Note • It is recommended that you use the ^RF, ^RM, ^RR, and ^WV commands rather than
the
^WT command. The ^WT command is provided only for backward-compatibility with
label formats that were developed for other Zebra RFID printers.
Important • Check the amount of data memory available for the tag that you will be using. If
more is sent than the memory can hold, the printer truncates the data.
Parameters Details
b = block number This parameter is tag-dependent. For most tags, use block 0. For EPC Class 0 Plus,
block 0 is EPC data, and block 1 is user data.
Accepted values: 0 to n, where n is the maximum number of blocks for the tag.
Default value: 0
r = number of
retries
Changes the number of times that the printer attempts to write to a particular block of
a single RFID tag. (Same function as the
^RR command.)
Accepted values: 0 to 10
Default value: 0
m = motion Enables or disables RFID motion. (Same function as the ^RM command.)
Accepted values:
• 0 (Feed label after writing.)
• 1 (No Feed after writing. Other ZPL may cause a feed.)
Default value: 0
w = write protect Accepted values:
• 0 (Not write protected.)
• 1 (Write protect.)
Default value: 0
