DLE EOT n
[Name] Real-time status transmission
[Format] ASCII DLE EOT n
Hex 10 04 n
Decimal 16 4 n
[Range] 1 ≤ n ≤ 4
[Description] Transmits the selected printer status specified by n in real-time, according to the following
parameters:
n = 1: Transmit printer status
n = 2: Transmit offline status
n = 3: Transmit error status
n = 4: Transmit paper roll sensor status
[Details] • The printer transmits the current status. Each status is represented by one-byte data.
• The printer transmits the status without confirming whether the host computer can receive
data.
• The printer executes this command upon receiving it.
• This command is executed even when the printer is offline, the receive buffer is full, or there
is an error status with a serial interface model.
• With a parallel interface model, this command can not be executed when the printer is busy.
This command is executed even when the printer is offline or there is an error status when
DIP switch 2-1 is on with a parallel interface model.
• When Auto 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. (Refer to Appendix G,
TRANSMISSION STATUS IDENTIFICATION)
• Even though the printer is not selected using ESC = (select peripheral device), this command
is effective.
[Notes] • The status is transmitted whenever the data sequence of <10>H<04>H<n>
(1 ≤ n ≤ 4) is received.
Example:
In ESC ∗ m n
L nH d1...dk, d1=<10>H, d2=<04>H, d3=<01>H
• This command should not be used within the data sequence of another command that
consists of 2 or more bytes.
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 3 interrupts
before n is received, the code <10>H for DLE EOT 3 is processed as the code for
ESC 3 <10>H.
