Highlighting is valid for character

font A (12x2

4) and

font B (9x16)

It is not recommended to be used for font B because text is not

readable. If at same time are given double height and/or double

width and to 90°-right-turning of character, then the sequense of

execution is as follows:

•

Characters is doubled in the direction indicated;

•

Character is turned at 90°-right-angle.

29. (ESC *) Printing graphical data

Code

[1Bh] + [2Ah] + m + n1 + n2 + D

+ … + D

Description

(0,1, 20h or 21h) Graphics mode (see table below).

0 <=

<= FF specifies the number of dots in horizontal line

(LSB).

0 <=

<= 09 specifies the number of dots in horizontal line

(MSB).

(

from 1 tо

)

Bit image data.

The number of dots in horizontal direction is

n1+n2*256

Number of data bytes

is:

n1 + 256*n2

for modes

and

(n1+256*n2)*3

for modes

20h

and

21h

The bits subject to printing are taken as

“1”

and those not as

“0”.

Bit image data is sent starting from the top to bottom and from the left to

right (vertical columns scanning). In modes

m=0 and

1 only

one byte

per column is sent and in mode

m=20h, 21h

–

3 bytes

for each column

are sent.
