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
