Escape sequence:		ESC	[	@	n1	n2	n3	n4	m1 m2
Hexadecimal:		1B	5B	40	n1	n2	n3	n4	m1 m2
where:
n1 n2	= byte count; format is (n1 + (n2 * 256))
n3 n4	= no function, ignored
m1	= line spacing and character height

Considerations for Using Enable/Diasble Double-High Double-Wide Print

Considerations for using the Enable/Disable Double-High Double-Wide command sequence are:

qThe byte count is usually four (4), when the count is greater than 4, the command is executed as per m1 and m2 and the additional bytes are accepted and ignored.

qWhen the byte count is three (3), the command is executed as per m1 only.

No m2 byte is provided, the character width remains unchanged. m1 is the last byte of the count.

qWhen the byte count is less than three (3) the command is accepted and ignored as follows:

byte count = 2 n4 is the last byte of the sequence

1n3 is the last byte of the sequence

0n2 is the last byte of the sequence
