[Notes]
•
The printer transmits [ Data + NUL] collectively without confirming whether the host
is ready to receive data. To receive all data correctly, adequate capacity is required in the
receive buffer of the host.
•
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.
