DLE ENQ n

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.
