ZPL II Commands for RFID
^WT – Write Tag
The format for the ^WT instruction is: ^WTb,r,m,w,s
where
^WT = Write Tag command
b = Block Number Default value: 0
Other values: 1 to n, where n is the maximum number of blocks for the tag
This is the starting block number. If the user sends more than a block of data it will overflow into the next block. If the user overflows the block and subsequent blocks cause errors (write protects, beyond range, etc.), the write will be aborted, but blocks already written will not revert to original contents. It’s up to the caller to ensure blocks aren’t accidentally overwritten.
r = Retries
Default value: 0
Other values: 1 to 10, number of retries
m = motion
Default value: 0 (Feed label after writing)
Other value: 1 (No Feed after writing, other ZPL may cause a feed)
w = Write protect
Default value: 0 (NOT write protected)
Other value: 1 (Write protect)
s = Special mode Reserved
