5 Transmit slip paper status
· The status information to be transmitted is shown in the tables on the following pages.
[Notes]
· The printer starts processing data upon receiving this command.
· When transmitting status, the printer transmits only 1 byte without confirming the
condition of the DSR signal.
· This command is executed even when the printer is off-line, when the receive buffer is
full, or when an error occurs.
· The status is transmitted whenever the data sequence of 10H (16), 04H (4), n (1£ n £5)
is received.
· This command should not be used within the data sequence of another command that
consists of 2 or more bytes.
· This command is unavailable when using the ESC = (select peripheral device) to select
the printer to be disabled.
· When Automatic Status Back (ASB) is enabled using the GS a command, the status
transmitted by the DLE EOT command and the ASB status must be differentiated using
the table in Appendix B, Transmit Status Identification .
· If the value of n is out of the specified range, the printer ignores this command.

Example:
If you attempt to transmit ESC 3 n to the printer, but DTR (DSR for the host
computer) goes to MARK before n is transmitted and then DLE EOT 4 interrupts
before n is received, the code 10H (16) for DLE EOT 4 is processed as the code for
ESC 3 10H (16) .
