3 Highlighting Canceled Specified
4 Double Height Canceled Specified
5 Double Width Canceled Specified
6 Undefined
7 Underline Canceled Specified
An underline is attached to the full character width, which, however, is not attached to the part having
been skipped by the horizontal tab. Neither is it attached to 90°-right-turned characters.
The underline width is as having been specified by (ESC -). (The default setting is 1 dot width.)
Highlighting is valid for character font A (12x24) 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. Printing graphical data ( ESC * )
Code: [1Bh] + [2Ah] + m + n1 + n2 + D
1
+ … + D
k
m (0 ,1 ,20h или 21h) Graphics mode (see table below).
0 <= n1 <= FFh specifies the number of dots in horizontal line (LSB).
0 <= n2 <= 09h specifies the number of dots in horizontal line (MSB).
D
i
( i from 1 to k ) bit image data.
The number of dots in horizontal direction is n1+n2*256 .
Number of data bytes k is n1 + 256*n2 for modes 0 and 1, and (n1+256*n2)*3 for 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.

When the values set in m or n2 are out of the above range, the data is processed as normal
printing data.
If some part of the graphic or the entire graphic is outside the printable area, then graphics data are
accepted, but only the needed part of them are printed.
In page mode and rotated by 90 degrees page the max. dot count is larger than the numbers in the table
above.
This command has one more version with 3 new modes:
Code:
[1Bh] + [2Ah] + m + n + { a + [00h] } +D
1
+ … +D
k
Designates a bit image of n*8 dots horizontal and by 24 or a dots vertical. Depending on m there is
compression of data. All 3 modes are with high dot density (203x203 dpi).
m can be:
10h Not compressed data with height 24 lines. Byte a and byte 00h are not sent.
11h Compressed data with height 24 lines. Byte a and byte 00h are not sent.
12h Compressed data with height a lines ( a <=24).
0 <= n <= FFh defines horizontal size.
