TM–U590/U590P Information Manual
With a parallel interface model, the default setting is n=1.
DLE ENQ n
[Name] Real-time request to printer
[Format] ASCII DLE ENQ n
Hex 10 05 n
Decimal 16 5 n
[Range] 1 ≤ n ≤ 3
DLE ENQ n responds to a request in real time from the host computer, specified by n as shown
below. n can be set to 1 or 2 only when a recoverable error occurs. This command is also executed to
recover from a recoverable error when the printer is disabled by ESC =.
For the TM-U590/U590P with the MICR reader, n can be set to 3 only when the printer is in the check
paper or cleaning sheet insertion waiting status. The check paper or cleaning sheet insertion waiting
status can be confirmed by the DLE EOT BS command. During transmitting check paper reading
result, this command is ignored.
When a recoverable error occurs, after removing a cause of an error, the printer can recover from an
error without turning off the power.
With a serial interface model, this command is executed even when the printer is off-line, the receive
buffer is full, or an error occurs.
