Draft document

• The remainder is Ln.

•

V1 though Vn represent graphics data.

•

m is a one-byte value to select the graphics mode. The following modes are
supported:

Set Graphics Line Spacing (n/216")

This command sets line spacing to n/216 inches. It does not cause the form to move.
It changes the vertical distance moved when a line feed command is received.

USAGE NOTES

•

The value of n can be from 1 to 255 (decimal), 01 to FF (hexadecimal).

Note:

The graphics data is organized by byte. For 8-wire modes, it is arranged and mapped to the wires identically to ESC K. For
24-wire modes, the data has three bytes per slice, with the most significant bit of he first byte mapping to the top wire and the
least significant bit to of the third byte mapping to the bottom wire. The slices are in sequence from left to right.

Modes 2,3 and 12 use consecutive dot elimination. No two adjacent horizontal dots can be printed. The second is
eliminated. For high resolution mode (8,9,11 and 12), the count should be: 1+(3 number of slices).

For 48-wire modes, the data has six bytes per slice.

However the 48-wire image is mapped to the 24-wire head by ORing bits 1 and 2 to wire 1, bit 3 and 4 to wire 2, and so on.
