the host becomes free more quickly, and the number of jobs that
the printer can accept simultaneously is increased. So increasing
this client can be beneficial in reducing network traffic, but
throughput speed is not necessarily increased. If available, a hard
drive can supplement this client with additional memory needed
for spooling. See “Hard Disk Management,” later in this appendix.
PostScript Font Cache
Listed as K Mem PS Fonts in the Administration/Memory menu
and also as Font Cache, this memory client stores bitmapped
representations of previously rasterized PostScript fonts, which
reduces the number of times a font must be converted from outline
form to bitmap form, so that pages print faster.
As the font cache memory fills, the printer erases bitmapped
characters to make room for new characters. By increasing the
memory allocated to this client, the printer can store more
characters and spend less time erasing and replacing characters in
the cache.
Normally, you do not need to change this memory client unless you
use a large number of fonts at different point sizes. There is no
specific formula to use in figuring the amount of memory required
by the font cache, but after a certain point, large font caches cause
printing to take longer than smaller font caches because of the
search time through the cache. The recommended font cache size
is 128-256 KB, but you should experiment to see what font cache
size works best for you.
Emulation
Listed as K Mem Emulation in the Administration/Memory menu,
this memory is used to store any optional (loadable) emulations.
