Notes:
• There are two kinds of maintenance counters: resettable counters and
accumulation counters. A resettable counter is a maintenance counter
that can be initialized by GS g 0, and an accumulation counter indicates
the counter value from when the printer starts operation.
• When a counter reaches its maximum value, its value is reset to 0 in the
next updating process.
• Unsupported counter numbers cannot be specified.
• The maintenance counter value consists of [Header + data + NUL], as
follows:
• Header: Hexadecimal = 0x5F/Decimal = 95: 1-byte data
• Data: Counter value = 0x30~ 0x39/Decimal = 48~ 57: 1-byte data
• NUL: Hexadecimal = 0x00/Decimal = 0: 1-byte data
