or status data back to the PC. Do not transmit more data from the PC until the
corresponding data is received from the printer.
• When operating with a serial interface, be sure to configure operation so that the
host computer uses these functions only when it is READY.
• With a parallel interface, a [Header ~ NUL] is stored at first in the transmission
buffer of the printer with the other transmission data (except for ASB status). When the
host enters Reverse Mode, the data is transmitted in order from the beginning. Data
that exceeds the transmission buffer size (99 bytes) is ignored. When using the
command, the host should enter Reverse Mode immediately and execute receive
processing of status.
■
When communication with the printer uses XON/XOFF control with serial interface, the
XOFF code may
interrupt the “Header to NUL” data string.
■
The information for each function can be identified to other transmission data according to
specific data of the transmission data block. When the header transmitted by the printer is
[hex = 37H/decimal =55], treat NUL [hex = 00H/decimal =0] as a data group and identify it
according to the combination of the header and the identifier.

The symbol data specified by Function 180 d1...dk is stored in the printer and is printed by
the specification of Function 181. The symbol data in the symbol storage area is reserved
until the following processing is performed:
