Simple Raster Graphics

Simple Raster Graphics prints a horizontal raster of graphics data one or multiple times. Horizontal offset and number of data bytes are variable and specified by parameters. This is a legacy support command and intended to be replaced by horizontal graphics commands. This command does not support compression or color graphics.

Description The [ESC]. command is a simple method of printing raster graphics, however the format does not support compression or color.

Where:

m:horizontal offset from left margin = 8 x m dots

n:number of data bytes that compose the raster

r : number of times the raster is to be printed = 256x rH + rL

d1…dn: data bytes

Range: 0<= m <= 80

0<=n<=80 0<= r <= 65535

0<= d1..dn <= 255

Note: This command can produce graphics that are difficult to print and hard on the power supply. Avoid multi-line repeats of very dark lines. In normal graphics, the printer does a look ahead at impending print and tries to adjust it’s speed to limit power consumption. This command can easily produce graphics that make that very difficult. For example a completely white space followed by a black group of lines that are less than 20 lines long will provide a transient load on the power supply that may overload it. The printer does not recognize the black data until it is too late to slow down. Normal graphics generally does not contain that kind of data.
