Bit 3 : If these errors occur due to paper jams or the line, 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.
