Control commands list

DLE ENQ n

[Name]	Real-time request to printer
[Format]	ASCII	DLE	ENQ	n
	Hex	10	05	n
	Decimal 16		5	n
[Range]	n = 0, n = 2
[Description]	The printer responds to a request from the host specified by n.
	n = 0: Recovers to on-line state.
	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

ESC ! n

[Name]	Select print mode(s)
[Format]	ASCII	ESC	!	n
	Hex	1B	21	n
	Decimal 27		33	n
[Range]	0 ≤ n ≤ 255
[Description]	Selects print mode(s) using n as follows:
Bit	Off/On	Hex	Decimal		Function
0	Off	00	0		Character font A (12 x 14) selected.
	On	01	1		Character font B (12 x 12) selected.
1	-	-	-		Undefined.
2	-	-	-		Undefined.
3	Off	00	0		Emphasized mode not selected.
	On	08	8		Emphasized mode selected.
4	Off	00	0		Double-height mode not selected.
	On	10	16		Double-height mode selected.
5	Off	00	0		Double-width mode not selected.
	On	20	32		Double-width mode selected.
6	-	-	-		Undefined.
7	Off	00	0		Underline mode not selected.
	On	80	128		Underline mode selected.

[Notes]

	When both double-height and double-width modes are selected,
	quadruple size characters are printed.
	Underlining is added to the entire width of each character,
	including the space to the right of a character, but is not added to
	portions of lines that were skipped by means of an HT.
[Default]	n = 1
