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

⁄

" 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
