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 one compressed block for a normal 8.5" x 11" (215.9 mm x
279.4 mm) text page, four 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 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 compressed block is printer
specific. The QMS 4060 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.
Increasing the amount of memory in this client may improve printing
throughput and minimize slowdowns due to collating or printing com-
plex pages. If your QMS 4060 Print System has a hard drive and the
disk swap option is enabled the memory added to this client is taken
from virtual memory. If your printer does not have a hard drive then
the memory added to this client is taken from the amount of physical
memory in your printer. It may be necessary to reduce memory added
to another client before adding memory to the Display List. Check that
the Frame Buffer still has the minimum amount of memory needed for
your printing needs before reallocating this memory.
