liquid crystal display (LCD) The LCD is a back-lit display that provides the user with
either operating status during normal operation or option menus when configuring the printer
to a specific application.
lock-up This is the term generally used to describe a fault condition that, for no apparent
reason, causes the printer to stop working. THIS COMMAND IS NOT FOUND IN ZPL
GUIDE.
media Material onto which data is printed by the printer. Types of media include: tag stock,
die-cut labels, contin uous labels (with and without media liner), non-continuous media,
fanfold media, and roll media.
media sensor This sensor is located behind the printhead to detect the presence of media
and, for non-cont inuous media, th e position of th e web, hole, or not ch used to indic ate the start
of each label.
media supply hanger The stationary arm that supports the media roll.
non-continuous media Media that contains an indication of where one label/printed
format ends and t he next one begins. Examples are die-cut lab els, notched tag-sto ck, and stock
with black mark registration marks.
non-volatile memory Electronic memory that retains data even when the power to the
printer is turned off.
notched media A type of tag stock c on tai ning a cutout area that can be sensed as a start-of-
label indicator by the printer. This is typically a heavier, cardboard-like material that is either
cut or torn away from the next tag. (See non-contin uo us media.)
peel-off A mode of operation in which the printer peels a printed label away from the
backing and allows the user to remove it before another label is printed. Printing pauses until
the label is removed.
print speed The speed at which printi ng occurs. For ther mal transfer printers, this speed is
expressed in terms of ips (inches per second).
printhead wear The degradation of the surface of the printhead and/or the print elements
over time. Heat and abrasion can cause printhead wear. There f ore, to maximize the life of the
printhead, use the lowest print darkness setting (sometimes called burn temperature or head
temperature) and th e lo w est p rint he ad p r essure necessary to produce good p ri nt qu ali ty. In the
thermal transfer printing method, use ribbon that is as wide or wider than the media to protect
the printhead from the rough media surface. THIS COMMAND IS NOT FOUND IN ZPL
GUIDE.
registration Alignment o f printing with re spect to the to p (vertical) or side s (horizontal) of a
label or tag.
ribbon A band of material consisting of a base fi lm coated with wax or resin “ink.” The
inked side of the material is pressed by the printhead against the media. The ribb on transfers
ink onto the media when heated by the small elements within the printhead. Zebra ribbons
have a coat ing on the back that protects the prin thead from wear.
