Graphics Commands

These commands are used to control the way graphics are entered or printed. They are listed in numerical order of their
hexadecimal codes.

Graphics

E
nters graphics printing mode which prints all available dots (uses all wires in the printhead). Any combination of
dots may be printed in a graphics cell. Each graphics cell is eight dots wide by nine dots high, with nine bytes of data
needed to define the cell (each byte defines the row of eight dots). The command must precede the nine bytes that
define the cell. Graphics and text may be printed on the same line.
Do not use the command again to turn off this graphics mode as the printer will expect another set of bytes to define
a new cell.

The following representation of the graphics cell shows how the cell is defined and which bits define which dots in the
cell (bit 0 is the least significant bit; bit 7 is the most significant bit).

Each line may have up to 25 graphics cells (full-dot graphics). The print line is printed unidirectionally.
Use six Vertical Tab commands (0B) or one Line Feed command (0A) between each line (8 lines/inch).

Graphics: 5 Dot

Enters or exits graphics printing mode which prints only the top five dots of the column (corresponding to the top five
wires of the printhead). These top five dots correspond to the least significant five bits (bits 0-4) of the data sent to the
printer as shown in the table.

Use the following characters to define the graphics (least significant five bits):
Hexadecimal: 20-3F
Decimal: 32-63
