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).
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.
