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.

off line

When the printer is off line, it cannot communicate with the computer.

on line

When the printer is on line, it is able to communicate with the computer.
