The

are described in each function.
[Notes]
The function is specified with the function code (
fn
). Details of the performance differ according to the
function.
[Notes for transmission process]
Transmission process is performed by <Function 082>, <Function 182>, and <Function 282>. When you use
this command, obey the following rules.
After the host PC transmits the function data, the printer will send response data 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.
