Digital Front End (DFE) Description
When a customer prints, the motherboard and printer interface board process image data. e printer interface
board is a custom board that allows the EX Print Server to communicate with the printer. e CPU controls the
transfer of image data to and from the motherboard and runs the PostScript interpreter. Dual in-line memory
modules (DIMMs) hold image data during printing
e interpreter rasterizes the page description file and compresses the image pattern into memory using
compression technology. e interpreter outputs the compressed raster data through the image frame buffer
memory to the printer interface board. e raster data is sent to the printer, which then renders the image on paper
at maximum speed.
