Frame Buffer
The Frame Buffer memory client holds rasterized or bitmapped 
images of page faces which are ready to be sent to the print engine. A 
frame holds the contents of each single page image. For example, a 
600 dpi page printed on letter size paper would consume frame buffer 
memory space as follows: (600dpi x 600dpi x 8.5 in x 11 in) /8 = 
4,207,500 bytes or 4.1 MB.
Because the frame buffer memory is so critical to the actual printing 
of a page, its allocation takes precedence over that of other memory 
clients. The number of frames needed to print at engine speed is 
engine specific and depends on the size media and resolution. For 
example, printing at 600x600 dpi requires four times the amount of 
memory in the frame buffer than does 300x300 dpi.
Minimum Frame Buffer Size
The following table lists the minimum number of KB that must be 
devoted to the frame buffer for all media size and resolution combina-
tions.
