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.
