ITEM SYMBOL Hexadecimal Decimal FUNCTION
[57] ESC [ \ n1 n2 [1B,5B,5C,n1,n2,m1,...m4] H Sets basic line spacing to 1/180", 1/216", or 1/360".
m1...m4 [27,91,92,n1,n2,m1,...m4] D n1=4, n2=0, m1=0, and m2=0
The basic line spacing affects the amount of the line
feeding at ESC J and ESC 3.
[58] ESC [ d n1 n2 [1B,5B,64,n1,n2,m] H Selects print character quality.
m [27,91,100,n1,n2,m] D n1=1 and n2=0
m=00h: no change
m=01h-7Fh: draft character quality
m=80h-BFh and FFh: LQ character quality
m=C0h-FEh: emphasized LQ character quality
[59] ESC [ g n1 n2 [1B,5B,67,n1,n2,m,data] H Sets various graphic modes.
m data [27,91,103,n1,n2,m,data] D
Note (**): Horizontal adjacent dots can not be printed.
The number of data bytes following n1 and n2 is defined as the total column number for
8-pin graphics (one byte/column) plus one extra parameter byte (m). 24-pin graphics
takes three bytes/column and 48-pin graphics takes six bytes/column.
Each bit data in the 8-pin and 48-pin graphics corresponds to 2 print pins of the print
head. The following figure shows one column of data and its corresponding print
position.
Note (
*)
: These pins become active when both adjacent print pins are activated.
[60] ESC \ n1 n2 [1B,5C,n1,n2,data] H Prints characters from all character set.
data [1B,92,n1,n2,data] D The number of character to be printed is defined by
n1+n2
×
256.
[61] ESC ] [1B,5D] H [27,92] D Reverse line feeds by the current line spacing.
[62] ESC ^ n [1B,5E,n] H [27,94,n] D Prints one character (n: character code) from all
character set.
[63] ESC _ n [1B,5F,n] H [27,95,n] D Sets or cancels overscore mode.
n=0: the overscore mode is cancelled
n=1: the overscore mode is set
[64] ESC d n1 n2 [1B,64,n1,n2] H Sets relative print position.
[27,100,n1,n2] D (n1+n2

256)/120" from current position
[65] ESC j [1B,6A] H [27,106] D Stops printing and sets the printer in offline.
