intermediate blocks of compressed data. Increasing the allo-
cation for this client increases chunk collation size and the
number of jobs that can be compiled ahead.
Disk Cache Client
The disk cache client stores frequently used data in system
memory instead of continually storing and retrieving it from a
hard disk. If a lot of hard disk access is required, adding
memory to the disk cache may increase the printer's perfor-
mance.
Context Switching
Context switching allows Crown printers, when memory limitations
permit, to preserve the state of an emulation (including downloaded
fonts, forms, logos, macros, overlays, and other data) when you
switch from one printer language or emulation to another. Many other
printers do not have this capability and erase downloaded fonts and
settings each time a user switches languages. Because the process
of downloading fonts and forms can be very time-consuming, context
switching significantly increases performance in environments where
multiple emulations are used.
Spooling Overflow
When a hard disk is attached to your printer, spooled print jobs can
transparently spill over to the hard disk, so buffers are not limited to
RAM capacity.
