PostScript Heap Memory
This is the amount of memory (KB) dedicated to the PostScript emulation
interpreter. This memory holds downloaded PostScript emulation fonts,
operators, and forms. The size range and default varies depending upon
the amount of memory available on your system. This memory client is
also known as virtual memory.
Inefficiently coded PostScript jobs can consume an infinite amount of
virtual memory or leave objects in the PostScript heap after the print jobs
are completed, leading to virtual memory errors. If not enough memory is
allocated to the PostScript heap, the job cannot print.
Increasing the memory allocated to this client allows more complex jobs to
print and increases the number of fonts that can be downloaded to virtual
memory. If you receive a virtual memory error when attempting to print a
job or download a font, this client should be increased in small increments
until the error message goes away.

PostScript Fonts Memory
This is the amount of memory (KB) dedicated to caching previously scaled
bitmap representations of fonts for the PostScript emulation interpreter.
This reduces the number of times a PostScript font must be converted
from outline form to bitmap form, thus reducing processing time. The size
range and default varies depending upon the amount of memory available
on your system. It is listed as Font Cache on the status page.
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. You
should experiment to see what font cache size works best for you.
