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
