When the values set in

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

+ … +D

Description Designates a bit image of

n*8

dots horizontal and by

dots

vertical. Depending on

there is compression of data.

All 3 modes are with high dot density (203x203 dpi).

can be:

10h

11h

12h

Not compressed data with height 24 lines.

Byte

and byte

00h

are not sent.

Compressed data with height 24 lines.

Byte

and byte

00h

are not sent.

Compressed data with height

lines.

0 <=

<= FFh Defines horizontal size.

The bit image data

Their number is

n*24

bytes for mode

10h

. The compressed data in

mode 11h must give same number of bytes, but after the

decompression. The number of data bytes for mode

12h

must be

a*n

(after decompression).

Decompression in modes

11h

and

12h

is similar to the one used in

PCX monochrome graphic mode. If the 2 most significant bits of the

consecutive byte are 1, so the next define a counter of iterations from

to 63

, and the next byte contains the data that has to be repeated.
