no physical pens, the lines it draws match
the attributes for pens numbered 1 through
8 in the application software. (See also

raster ą1. A matrix of dots, or pixels,
where each pixel is defined by a bit. A bit
that is on" will print a dot on the paper. A
bit that is off" will leave the area blank. 2.
A method for defining a plot directly in
terms of the pixels rather than as vectors.
resolution ąA measure of image sharpness
expressed as a number of lines per unit
length. When referring to plotters,
addressable resolution means the smallest
move the plotter can make
programmatically.
rms ąRoot mean square
