Chapter 1 EPSON/IBM Commands 19 260071 ‐ 001A
This command specifies the distance from the left margin to where you want to print subsequent
characters. The distance is in number of dots and must be calculated using the following formula:
Margin distance = n1 +(n2 x 256) where n2 is the integer result of the number of dots divided by 256 and
n1 is the remainder. 1 dot = 1/60 inch. If the selected position is outside the current right margin, the
sequence is ignored.
ESC[ \
Sets vertical units. (IBM)
ASCII Code
ESC [ \ m1 m2 t1 ... t4
Hexadecimal Value X'1B' X'5B' X'5C' m1 m2 t1 ... t4
Decimal Value 27 91 92 m1 m2 t1 ... t4
Range m1 =4
m2 =0
0 = t1 = 255
0 = t2 = 255
t3 =0
t4 = 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 \ n1 n2
Hexadecimal Value X'1B' X'5C' n1 n2
Decimal Value 27 92 n1 n2
Range 0 = n1, n2 = 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 = n1 +(n2 x 256)
where n2 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 m2 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 n1 +(n2 x 256).
