How the imagePRESS Server operates

When a customer prints, the motherboard and printer interface board process image data. The printer interface board is a custom
board and allows the imagePRESS Server to communicate with the printer. The CPU controls the transfer of image data to and
from the motherboard and runs the PostScript interpreter. DIMM holds image data during printing.
Using compression technology, the interpreter rasterizes the page description file and compresses the image pattern into memory.
The interpreter outputs the compressed raster data through the image frame buffer memory to the printer interface board. The
raster data is sent to the printer, which then renders the image on paper at maximum speed.
