How the Fiery ES operates
When a customer prints, the motherboard processes image data. The CPU, which is located on the motherboard, controls
the transfer of image data to and from the motherboard and runs the interpreter. DIMMs, which are also located on the
motherboard, hold image data during printing.
The interpreter rasterizes the page description file and compresses the image pattern into memory using compression
technology. The interpreter outputs the compressed raster data through the image frame buffer memory to the printer
interface port. The raster data is sent to the printer, which then renders the image on paper at maximum speed.
