ESC $ n1 n2
Description: Horizontal dot positioning
Format: <1Bh><24h><n1><n2>
Comments: Dot positioning command in bytes (to be used with ESC V). Dot position equals (n1 +
256*n2). n1 must be less than the total number of the head bytes, given by the total
number of dots divided by 8 (CP305MRS is 576/8 = 72), and n2 is always 0.
ESC V n1 n2 n3 <data>
Description: Horizontal bit image
Format: <1Bh><56h><n1><n2><n3><datas>
Comments: The number of bytes to be printed is equal to (n2+256*n3). n2 must be less than the total
number of the head bytes, given by the total number of dots divided by 8 (EPM205-MRS
is 384/8 = 72), and n3 is always 0. n1 is the resolution: 0 is standard size,1 is double
width, 2 double height, 3 is expanded.
IMPORTANT NOTES FOR GRAPHICS:
·
Please note that n4 (offset) + n5 (graphic width) needs to be less than the number of head’s bytes
(printing width). If it is greater, control code will be ignored.
·
One dot line must be performed in less than 2s. If not, the current into stepper motor will be removed
resulting in poor print quality.
·
It is recommended for all graphics sequences to set up the communication speed at the maximum
value.
