If an ENQ is received after the print job specified in the ID bytes has been completed,
or there is no data in the buffer, the printer will respond with two “space” characters
(20 hexadecimal) for the ID number, six “zero” characters (30 hexadecimal) in the
Remaining Labels bytes and the 16 byte Job Name.
Cancel (CAN)
If a CAN (18 hexadecimal) command is received , it will stop the print job and clear
all data from the receive and print buffers. A delay of five milliseconds or more is
required before any new data can be downloaded. The CAN command is effective
immediately upon receipt, even if the printer is off-line or in an error condition. The
printer will return an ACK (06 hexadecimal) if there is no printer error condition and
a NAK (15 hexadecimal) if an error condition exists.
Print Job
Upon receipt of a valid print job (<ESC>A . . . <ESC>Z),anACK (06
hexadecimal) will be returned by the printer if there are no errors and a NAK (16
hexadecimal) if a printer error exists.
Print Stop (DLE)
If a DLE (10 hexadecimal) is received by the printer, the print process is stopped and
an ACK (06 hexadecimal) is returned if there are no errors and a NAK (16
hexadecimal) if a printer error exists.
PrintStart(DC1)
If the printer has been stopped by receipt of a DLE (10 hexadecimal) command, it
can be restarted by sending a DC1 (hexadecimal 11) command. Upon receipt of this
command an ACK (06 hexadecimal) is returned if there are no errors and a NAK (16
hexadecimal) if a printer error exists.
(1) To provide compatibility with older SATO printers, the RS232 interface can be
configured to use an earlier ENQ/ACK/NAK protocol. The earlier protocol did not
have provisions for the Job Name and did not respond to the DLE or DCI
commands. Also, there are additional Response Codes in the Status Byte Definition.
It is recommended that you use the current protocol rather than the earlier version
unless it is necessary for compatibility with existing software.
