Prints normal-density graphics.
277.5 nl n2 ml m2 .....
IB 4B nl n2 ml m2 .....
This command selects 60 dots-per-inch, column-scan, bit-image graphics mode. The values of nl and n2 represent the number of graphics characters to be printed, where the total number of characters = n2 times 256 + nl. The correct number of graphics data bytes (ml, m2, etc.) must follow n2. The ASCII values of these bytes determine which pins are fired for each character.

Prints double-density graphics.
2776 nl n2 ml m2 .....
IB 4C nl n2 ml m2 .....
This command selects 120 dots-per-inch, column-scan, bit-image graphics mode. The values of nl and n2 are the same as in normal-density graphics. The correct number of graphics data bytes (ml, m2, etc.) must follow n2. The ASCII values of these bytes determine which pins are fired for each character.
