emulation client. After changing the memory configuration, print
a status page to ensure the frame buffer has enough memory.
Display List
Also known as K Mem Display, this client shares its memory with
the excess memory client. The display list stores compressed
representations, or blocks, of the pages to be printed. It takes
approximately 1 compressed block for a normal 81/2" x 11" text
page, 4 compressed blocks for an 8
1
⁄
2
" x 11" 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.
Your printer takes approximately 64 KB of memory from the
display list for each compressed block.
Increasing the amount of memory in this client may improve
printing throughput and minimize slowdowns due to collating or
printing complex pages. If not enough memory is allocated to this
client, memory is taken from the excess memory client to complete
a print job.
PostScript Font Cache
Also known as K Mem PS Fonts and Font Cache, this memory
client stores bitmapped representations of previously scaled
PostScript fonts. This process reduces the number of times a font
must be converted from outline form to bitmap form. Printing pages
