Description
The printer uses standard random access memory (RAM)
to buffer temporarily user data during simple print and
copy jobs.
The printer may use two forms of non-volatile memory:
EEPROM and NAND (flash memory). Both types are used
to store the operating system, printer settings, network
information, scanner and bookmark settings, and
embedded solutions.
Some printers may have a hard disk drive installed. The
printer hard disk is designed for printer-specific
functionality. The hard disk lets the printer retain buffered
user data from complex print jobs, form data, and font
data.
