n = 3: Transmit error status
n = 4: Transmit paper roll sensor status
[Details] · The status is transmitted whenever the data sequence of <10>H<04>H< n>
(1 £ n £ 4) is received.
Example:
In ESC * m nL 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.
· Even though the printer is not selected using ESC = (select peripheral device),
this command is effective.
· The printer transmits the current status. Each status is represented by onebyte
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 off-line, 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 off-line 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.
