BCC Check Function
BCC (Block Check Code) is 1 byte of data calculated XOR of 1 send data (<A>-<Z>). BCC shall be
added to the end of data (<Z>) per item for host to send data to this product.
This product checks the validity of receiving data by calculating BCC per data item being received
and compares it with sent BCC. When those BCC are different, this product judges that receiving
data is incorrect and causes [BCC error] before printing the item then stops printing operation.
