Printer page composition with color and text

摘要

Page description information received from an interpreter is composed into color plane memories as basic pels for line information and larger, 4 by 2 basic pels for color information, with intensity information for larger color pels also in the color plane memories. A separate color pel memory stores the meaning of the larger pels. Intensity is printed by filling parts of the 4 by 2 color pels as dictated by the intensity information.
