Bit 3: If these errors occur due to paper jams or the like, it is possible to recover by correcting the cause of the error
and executing DLE ENQ n (1 ≤ n ≤ 2). If an error due to a circuit failure (e.g. wire break) occurs, it is impossible
to recover.
Bit 6: When printing is stopped due to high print head temperature until the print head temperature drops sufficiently
or when the paper roll cover is open during printing, bit 6 is On.

Request
1
Recover from an error and restart printing from the line where the error occurred
2
Recover from an error aft clearing the receive and print buffers
[Details]
This command is effective only when an auto-cutter error occurs.
The printer starts processing data upon receiving this command.
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.
The status is also transmitted whenever the data sequence of <10>H<05>H< n> (1≤n≤2) is
