The following table lists, for your information, the minimum number of
KB that must be devoted to the frame buffer for all media size and
resolution combinations:
Display List
Also known as K Mem Display, this client stores compressed repre-
sentations, or blocks, of the pages to be printed. It takes approxi-
mately 1 compressed block for a normal 8.5" x 11" (215.9 mm x 279.4
mm) text page, 4 compressed blocks for an 8.5" x 11" (215.9 mm x
279.4 mm) page that includes some graphics, and as many as 500
compressed blocks for an extremely complex page.
Many pages of compressed blocks (R1 blocks) belonging to multiple
print jobs can be stored at the same time in the display list. If enough
memory is allocated to this memory client, a page can always be
ready to print as soon as another page has been imaged to the print
engine.
The amount of memory required for each R1 block is printer specific.
The QMS 1060 Print System takes approximately 64 KB of memory
from the display list for each compressed block. However, if a page
includes raster image data (for example, TIFF or bitmap data), each
compressed block will require much more memory.
