Your printer provides RS-232C serial communications. See also
parallel
interface.
SIMM (Single In-line Memory Module)
A small circuit board designed to accommodate surface-mount memory
chips. SIMMs use less board space and are more compact than more
conventional memory-mounting hardware. See also
memory upgrade.
SIO (Simultaneous Interface Operation)
The capability of printing to all three of the printer's concurrently active ports
rather than being restricted to one. See also
concurrent interfaces.

memory and remain available to be used until the printer is turned off. See

rary storage to hold print jobs until the printer is available to process them.

current interface settings, and amount of RAM available.
