print quality

Your printer has two types of print quality: draft and Letter Quality

(LQ). Draft is for high-speed, draft quality jobs; LQ is used to

produce more polished documents.

proportional printing

Printing in which the character width varies from character to

character. For example, a capital W receives much more space than a

lowercase i. The result looks more like a typeset book than a

typewritten draft.

push tractor unit

An optional device that moves continuous paper through the

printer.

RAM

Random Access Memory. The portion of the printer’s memory used

as an input buffer and for storing user-defined characters,

downloaded fonts, and graphics images. Information stored in RAM

is volatile and is lost when the printer power is interrupted.

reset

To return a printer to its defaults, either by a command, interface

signal, RESET button, or by turning the printer off and on.

ROM

Read Only Memory. The portion of the printer’s memory that is

permanent. Information stored in ROM is used to control how the

printer operates. Resident fonts are also stored in ROM.

SelecType

A feature of the printer that allows you to set printer values and

control most of the printer’s functions from the front panel.

serial interface

See interface.

status sheet

A report that lists the settings and other printer information. You

can print this report using the SelecType feature.
