There’s 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 the printer to take longer to print than smaller font caches
because of the search time through the cache. The recommended
font cache size is in the following ranges:
„
128-256 KB for 300x300 dpi printing
„
256-512 KB for 600x600 dpi printing
„
384-512 KB for 1200x1200 dpi printing
You should experiment to see what font cache size works best for
you.

Also known as K Mem PSHeap, Heap, PostScript VM, and Virtual
Memory, this client holds downloaded fonts, PostScript operators, and
forms.
Inefficiently coded PostScript jobs can consume an extremely large
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 PS 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 down-
loaded to virtual memory. However, this client should be increased
only if you receive a virtual memory error when attempting to print a
job or download a font, and even then it should be increased only in
small increments until the error message goes away. Excess memory
in the PS heap is not used.

Also known as K Mem Emulation, this client is used to store any
optional or loadable emulations, such as LN03 Plus or QUIC II.
Increasing this client’s memory allows you to load more than one
optional emulation so that it doesn’t have to be reloaded every time
the print job is sent.
