memory
The part of the printer’s electronic system that is used to store
information. Some information is fixed and is used to control how
the printer operates. Information that is sent to the printer from the
computer (such as downloaded fonts and graphics) is stored
temporarily until it is printed out. See also RAM and ROM.
menu
In the SelecType mode, you can change sixteen kinds of settings in
your printer, such as the paper size or font source. These sixteen
settings are called menus. See also option.
number systems
Three number systems are commonly used with printers:
decimal
is base 10 and uses the digits 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9.
This is the most familiar system.
hexadecimal
(hex) is base I6 and uses the digits 0, 1, 2, 3, 4, 5, 6,
7, 8, 9, A, B, C, D, E, and F. This is frequently used by
programmers. Any decimal number between 0 and 255 can be
expressed by a two-digit hex number.
binary
is base 2 and uses only the digits 0 and 1. All information
in computer systems is handled in binary form to represent
electrical signals that are on or off. A binary digit is often called
a bit; any decimal number between 0 and 255 can be expressed
by an eight-bit binary number.

computer.
