QMS Memory Definitions
Before you can configure your printer's memory efficiently, you must
first understand the different types of memory and how they work
together. QMS Crown documentation uses the following memory
terms:
Memory—Memory allows your printer to store and retrieve informa-
tion. It is the space within your printer where information is stored
while being actively worked on.
Memory Clients—A memory client is a block of memory dedicated to
a specific function. Each memory client controls certain features.
When insufficient memory is allocated to a specific client, the features
it controls may not be accessible.
Excess Memory Client—The memory remaining after providing all
the other memory clients with their specified amounts of memory is
automatically added to the excess memory client. The display list is
the excess memory client for the QMS 4525 Print System.
Storage—Storage is a device in or on which information can be kept.
There are three main types of storage, ROM, RAM and hard disk
drives. ROM stores read-only data, RAM represents temporary stor-
age, and hard disk drives hold information on a more permanent
basis (see the following definitions).
ROM (Read Only Memory)—This type of memory contains data
and/or machine-executable instructions that can be read but not mod-
ified. This information is not lost when the printer is turned off.
RAM (Random Access Memory)—RAM is the memory your printer
uses to perform each task. The QMS 4525 Print System has 32 MB of
RAM. It can be written to and read from. Once a task is complete, the
memory is free again to be used for another file. This memory is vola-
tile, so if your printer loses power while a file is being sent, you must
resend the file. The number and type of features you can run on your
printer simultaneously depend on the amount of RAM your printer has
and how that RAM is distributed.
RAM Disk—Also called a virtual disk, the RAM disk is an area of
RAM that is used to simulate an additional hard disk. Data can be
