wsb: Specify write start block
Normally, RFID write print jobs that don't include print
data writes but don't feed label. (Except for cases
with tag offset as default)
When 1 is specified for this parameter, even the print
jobs that don't include print data will feed.
When 0 is specified, print jobs that don't include print
data will not feed, which is the same as not specifying
fsw:. Also, printer only writes without feeding or
printing when 0 is specified for print jobs that include
print data, which allows write test without having to
waste label.
If don't feed, Short buzzer will sound 2 times when
write is successful. Short buzzer will the sound 6
times when it fails to write.
In addition, if 2 is specified for the item including
print data, a write test can be performed without
consuming label as only write is executed without
feed/print.
Valid range: 0-2

Data in the block outside for writing is
maintained.
* The remaining byte XXX will be filled with
NULL.
