ESC[\

Sets vertical units. (IBM)

ASCII Code ESC [ \ m

... t

Hexadecimal Value X'1B' X'5B' X'5C' m

... t

Decimal Value 27 91 92 m

... t

Range

0 ≤ t

= 180 or 216

This command changes the base units for the graphics line spacing commands (ESC J, ESC 3). The

default is 1/216 or 1/180 inch.

ESC /

Selects the Vertical Format Unit (VFU) channel. (EPSON)

ASCII Code ESC / m

Hexadecimal Value X'1B' X'2F' m

Decimal Value 27 47 m

Range 0 ≤ m ≤ 7

This sequence selects the VFU channel that you want to use. Eight different channels are available. The

m parameter represents the channel you want to select.

ESC \

Sets the relative dot position. (EPSON)

ASCII Code ESC \ n

Hexadecimal Value X'1B' X'5C' n

Decimal Value 27 92 n

Range 0 ≤ n

, n

≤ 255

This command specifies the distance between the current print head position and the position where you

want to print subsequent characters (relative position). The distance is a number of dots and must be

calculated using the following formula:

Current position distance = n

+(n

x 256)

where n

is the integer result of the number of dots divided by 256 and the n1 is the remainder. The unit of

dots is 1/120 inch for Draft or 1/180 inch for Letter Quality printing. If the distance is negative (Most

Significant Bit of m

equal to 1), the print head is moved to the left of the current position by the number of

dots equal to the complement on two of n

+(n

x 256).
