- CUSTOM GRAPHICS EXAMPLE
- 1. Determine the matrix size for the graphic. It must be in 8 dot by 8 dot blocks. The example here has six blocks horizontally and six blocks vertically (48 x 48).
- 2. Lay out a grid and draw the image on the grid.
- 3. Transfer the image into a bit map representation and then into hexadecimal format:
- 4. Using the hexadecimal data, send the following code to print the graphic image as designed.
- 5. To send the data in binary format, the software must convert the data into binary format before transmitting it to the printer. Using the BASIC programming language for example, this is done by notation “CHR$ (&HC0)” which sends the hexidecima...

GRAPHICS, BMP FILE
FUNCTION
To allow the creation and printing of graphic images using a BMP file format.
FORMAT
<ESC>GMaaaaa,(data)
aaaaa = Number of bytes to be downloaded and printed
Place anywhere within the job data stream.
EXAMPLE
<ESC>A
<ESC>V0100<ESC>H0100<ESC>GM03800,(...Data...)
<ESC>Q1
<ESC>Z
OUTPUT
(4-31)
NOTES
The maximum number of bytes that can be downloaded is 32K (compressed) and includes the BMP
header information. The maximum size of the uncompressed BMP file is 64K. If the uncompressed file
exceeds 64K, the graphic will not print.
Only black and white BMP files can be downloaded.
The file size specified by this command is the DOS file size in bytes.
