CONTROL COMMANDS LIST
Error status (n = 3) is as follows:

If mechanical error (bit 2) or auto cutter error (bit 3) occurs due to paper jams or the like,
it is possible to recover by correcting the cause of the error and executing DLE ENQ.
If an unrecoverable error (bit 5) occurs, turn off the power as soon as possible.
Paper sensor status (n = 4) is as follows:
Bit Binary Hex Decimal

DLE ENQ
[Name] Real-time request to printer
[Format] ASCII DLE
Hex 10
Decimal 16
[Range] n = 2
[Default] None
[Description] Recovers from an error after clearing the receive and print buffers.
[Notes] This is a real-time command that the printer executes upon receiving it.
Note the following when using this command.
- If this command is embedded within the code string of another command,
it is processed as a parameter of the other command, and the print result
is not correct.
- If another command (such as bit image or defined data) has a code string
in a parameter that is the same as this command, the printer starts
processing this command.
DLE ENQ 2 is enabled when a recoverable error occurs with the exception
of an automatically recoverable error, and is ignored in other cases.
With a serial interface model, this command is executed even when the
printer is offline or the receive buffer is full.
With a parallel interface model, this command is not executed in the following
conditions, because the printer is busy and unable to receive data from the
host computer. The busy condition is set by DIP Switch (DSW1-4).
- Receive buffer is full when DIP Switch (DSW1-4) is set to On.
- Printer is offline, an error occurs, or receive buffer is full when
DIP Switch (DSW1-4) is set to Off.
When a recoverable error occurs, after removing the cause of the error,
the printer can recover from the error by transmitting DLE ENQ 2 without the
printer being turned off.
DLE ENQ 2 is also executed to recover from a recoverable error when the
printer is disabled by ESC =.
After processing DLE ENQ 2, the printing position is moved to the left side
of the printable area. Printer is in the status "beginning of the line," or "there
is data in the print buffer."
This command is disabled while sending the block data "Header ~ NUL."
