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
NOTE: 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)
