Hello!
At the moment I am drawing up a composition about "Laserprinter" within my
training as IT- sales clerk.
In this compostion I want to include some examples to measure the memory
requirements the Raster Image Processor needs to create the raster image.
In case of black/white printing this calculaton is quite simple:
Width * dpi * Length * dpi * 1 Bit (<- either black is set or not)
This way of calculation was confirmed by a staff of Kyocera-Mita, too.

But how do you calculate the memory requirement of color-laserprinters. How
many bits are set for one dot there?
Is it only 1 Bit for: dot set / dot not set?
Or are there more bits like:
cyan dot set/ cyan dot not set
magenta dot set / magenta dot not set
....
Looking forward to your replies
Best regards
Johannes Hoffmann

Hi,

I'm not sure about other brands but I know that QMS / Konica-Minolta uses
the following for it's framebuffer:
Width * dpi * Length * dpi * 1 Bit * 4
