- 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...

Unit 6: Bi-Directional Communications
“i” Programming Reference
6-9 PN: 9001158B
SYSTEM VERSION INFORMATION (SB)
Receipt of SOH followed by SB causes the printer to return information bounded by an STX-ETX pair that reports
the system version of the printer.
Figure 6-6, Return Status/Format Diagram
MEMORY STATUS (EB)
Receipt of SOH followed by EB causes the printer to return information bounded by an STX-ETX pair that reports
the current user memory allocation.
