n = 3 : Error status

Bit	Off/On	Hex	Decimal		Function
0	Off	00	0		Not used. Fixed to Off.
1	On	02	2	Not used. Fixed to On.
2	Off	00	0	No mechanical error.
	On	04	4	Mechanical error occurred.

5	Off	00	0	No unrecoverable error.
	On	20	32	Unrecoverable error occurs.
6	Off	00	0	Automatic recover error.
	On	40	64	No automatic recover error.
7	Off	00	0	Not used. Fixed to Off.

Bit 2 : 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 2. If an error due to a circuit failure (e.g. wire break) occurs, it is impossible to recover.

DLE ENQ n

[Name]	Real-time request to printer
[Format]	ASCII	DLE	ENQ	n
	Hex	10	05	n
	Decimal	16	5	n
[Range]	n = 2
[Description]	The printer responds to a request from the host specified
	by n.

n = 2: Recovers from an error after clearing the receive and print buffers.

[Notes]

•This command should not be used within the data sequence of another command that consists of two or more bytes. For 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 DLE ENQ 2 interrupts before n is received, the code <10>H for DLE ENQ 2 is processed as the code for ESC 3 <10>H.

•This command n = 2 is valid only when a mechanical error or an auto- cutter error has occurred.

•DLE ENQ 2 enables the printer to recover from an error after clearing the data in the receive buffer and the print buffer.

The printer retains the settings (by ESC !, ESC 3, etc.) in effect when the error occurred. The printer can be initialized completely by using this command and ESC @. This command is enabled only for errors that have the possibility of recovery

ESC SP n

[Name]	Set right-side character spacing
[Format]	ASCII	ESC	SP	n
	Hex	1B	20	n
	Decimal	27	32	n
[Range]	0 ≤ n ≤ 255
[Description]	Sets the character spacing for the right side of the
	character to [ n x 0.122 mm {1/208 inches}] .
[Notes]	The right-side character spacing for double-width mode is
	twice the normal value.
[Default]	n = 0
