1.7 DEClaser 1100 and 1150 Printer Video Control Board
The DRAM is divided into the following three fields (the size is adjustable
through the control panel setup menu):
• The page (input) buffer contains data received from the host system.
• The page memory contains the image data bitmap or dot pattern data.
• The font cache memory contains processed fonts.
The read-only memory (ROM) holds the image data that makes up the internal
fonts and stores the firmware operating programs of the video control board.
