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.

moves
continuous paper through the
printer.

reset

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