GLOSSARY OF TERMS
Memory that retains information even when power is turned off. The
printer’s permanent memory retains the default settings specified
using the printer setup mode.
Characters per horizontal inch (cpi).
A hard rubber cylinder that moves paper forward during printing.
Character spacing in which wide characters occupy more space than
do narrow characters. For example, characters such as “W” or
“M”occupy more horizontal space than do characters such as “i” or
“l.” Many soft fonts are proportionally spaced. Sometimes
designated PS, proportional spacing is the opposite of monospacing.
A set of instructions that control how data is transmitted between
devices such as a computer and printer.
In rear feed, paper is fed from the rear of the printer. The forms
tractor unit pushes paper into the printer.
Fonts present (resident) in the printer’s permanent memory. For this
printer, the resident fonts are Courier 10, Prestige Elite 12, Pica 10,
OCR-B 10, OSR-A 10, Boldface PS, Compressed font,
Correspondence, Draft, and High-speed Draft. Unlike soft fonts,
resident fonts can always be accessed.
A type of serial interface. See Serial interface.
A test that determines whether the printer is working correctly. Test
pages are printed to show print quality and verify whether all
characters print. The self-test only tests the printer. It does not test
how thecomputer works with the printer.
A standard computer interface. Information is transferred between
devices over a single wire (although other wires are used for control).
A serial interface can use an interface cable greater than 3 meters (10
feet). A long cable is often necessary in networking environments,
where the printer may be shared.
