How the imagePASS 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
imagePASS 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.
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 board. The
raster data is sent to the printer, which then renders the image on paper at maximum speed.
