NUL 00H 0 1 byte
• During the transmission of block data values in the maintenance counter, the printer ignores
the real-time commands. Also, the printer does not transmit ASB even when the ASB is
enabled. Therefore, the user cannot confirm changes in the printer status during these periods.
• The counter values may be different from the actual counts depending on time differences at
power off or the occurrence of an error.
