Section 3: IBM Emulation Mode Printer Commands
Graphics Print Modes
Normal Density Bit Image Graphics
Use this command to print normal density bit images at 60 dots per inch (dpi)
horizontally and 72 dpi vertically.
Usage Notes
• Ln and Hn identify the number of bytes in data.
To print less than 256 bytes:
— Hn is 0.
— Ln is the number of bytes you want to print.
To print more than 256 bytes:
— Divide the number of bytes you want to print by 256.
— The result is Hn.
— The remainder is Ln.
• data is the bit-mapped graphics information.
Each vertical dot column can have 8 rows of dots. To print bit image graphics,
the printer uses either the first 8 (248x) or 20 (249x) wires of the printhead to
map the eight bits of data. The following table shows how the print wires are
mapped for the 249x printer:
