In single density, one byte (8-dots) is printed in each full dot column. In double-density, one byte is
printed in each half/full dot column, but adjacent horizontal dots (overlapping dots) are not printed.

Value of n:

Value of n (8-dot single-density mode) Value of n (24-dot single-density mode)

Value of d

n1 + (256 × n2)

3 x [n1 + (256

× n2)]

Number of bytes of data*

*Printed left to right (8-dot mode); Printed down then across (24-dot mode).

Formulas

8-dot single-density

n1 + (256 × n2)

24-dot single-density

3 x [ n1 + (256 × n2)]

Sets the print resolution and enters one line of graphics data into the print buffer. Excess data is accepted but ignored.
Any print command is required to print the data, after which the printer returns to normal processing mode.

See the illustration for graphic representations of the bit image on next page.

In A756 emulation mode, slip graphics are only seven dots high.

Value of m:

horizontal offset from left margin = 8 x m dots

Value of n:

number of data bytes that compose the raster

Value of r:

number of times the raster has to be printed =256 x rH + rL

d1 … dn:

data bytes

Range:

0<= m <= 72

0<= n <= 72

0<= r <= 65535

0<= d1 … dn <= 255

Prints a horizontal raster of graphics data one or multiple times. Horizontal offset and number of data bytes are
variable and specified by parameters.

Exceptions

Advanced raster graphics is not available in page mode.
