Spooling is temporary storage to hold print jobs until the printer is
available to process them.
The first step in allocating your printer's memory is to define your
printing needs. Each of your printer's features requires a minimum
amount of memory. If you use a feature, you must allocate enough
memory to the client which controls it. On the other hand, if there are
features you don't use, you can take the memory in the clients that
control the unused features and assign it to other clients that need
additional memory.
To get a better idea of what your printing requirements and your
printer's capabilities are, answer the following questions.
» Note: The memory clients or menu options associated with each
