·This command should not be used within the data sequence of another
command that consists of 2 or more bytes.
Example :
If you attempt to transmit
ESC 3
n
to the printer, but DTR (DSR for
the host computer) goes to MARK before
n
is transmitted and then
DLE EOT 3
interrupts before
n
is received, the code <10> H for
DLE
EOT 3
is processed as the code for
ESC 3
<10>H.

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.
