* After each packet is checked by CRC, the packets which pass the check are stored. When the
final block is received normally, an issue is started.
* 128 block Nos. can be set from 0 to 7F. (However, if the packet length is designated in 2
bytes, total data amount of all blocks must be 60 KB or less. Therefore, a maximum of 128
block Nos. may not be able to be set.) When 128 block Nos. (or 60 KB) are not enough,
terminate the command transmission, and issue the receipt. After issuing the receipt, the
remainder can be sent. If the next command packet is sent during an issue, it is discarded
without being processed.
* The block Nos. must be consecutive, starting from 0 (in ascending order). If the block Nos. are
not consecutive, starting from 0 in ascending order, a command syntax error occurs. If the
same block No. is received again before the final block is received, the block is discarded
without being stored.
* For the final block, the most significant bit must be cleared to 0. The printer starts an issue
after the final block is received. Therefore, if this setting is not made, the printer does not start
printing.
Block No. (0 to 7F)
Final block flag 0: Final
