Citizen Systems iDP-3551, iDP-3550 user manual ESC ∗ n1 n2, ESC − n, Esc

ESC "∗" n1 n2

[Function]	Specifying the bit image mode
[Code]	<1B>H <2A>H n1 n2
[Range]	1 ≤ n1 + 256 × n2 ≤ 360 (for DP654 mechanism)
	1 ≤ n1 + 256 × n2 ≤ 400 (for DP657 mechanism)
[Outline]	This command allows printing in the bit image mode. Divide the number of dots printed by
	256 and assume its quotient to be n2 and remainder to be n1. Therefore, the number of
	horizontal dots will be n1 + 256 × n2.
	If the bit image data is entered beyond the dot positions printable in one line, the surplus data
	will be discarded. Normal data processing is restored after bit image printing. Printing is
	done in a single direction.

ESC "−" n

[Function]	Specifying/Canceling the underline
[Code]	<1B>H <2D>H n
[Outline]	This command selects/deselects an underline. The underline is selected at n = 1 and
	deselected at n = 0.
[Default]	n = 0
ESC "1"
[Function]	Setting the 1/9-inch line feed width
[Code]	<1B>H <31>H
[Outline]	Only effective for Graphic type.
	This command sets the line feed width to 1/9 inch.
ESC "2"
[Function]	Setting the 2/9-inch line feed width

[Code] <1B>H <32>H
