Glossary
alphanumeric Indicating letters,
numerals, and characters such as
punctuation marks.
backfeed Backfeed is when the printer
pulls the media and ribbon (if used)
backward into the printer so that the
beginning of the label to be printed is
properly positioned behind the
printhead. Backfeed occurs when
you’re operating the printer in
tear-off, peel-off, or cutter mode.
bar code A code by which alphanumeric
characters can be represented by a
series of adjacent stripes of different
widths. Many different code schemes
exist, such as the universal product
code (UPC) or Code 39.
calibration (of a printer) A process in
which the printer determines some
basic information needed to print
accurately with a particular
media/ribbon combination. To do this,
the printer feeds some media and
ribbon (if used) through the printer
and senses whether to use the direct
thermal or thermal transfer print
method, whether continuous or
non-continuous media will be used,
and (if non-continuous media) the
length of individual labels/tags.
character set The set of all letters,
numerals, punctuation marks, and
other characters that can be expressed
by a particular barcode.
check digit A character added to a
barcode symbol that indicates to the
scanner that it has read the symbol
correctly.
continuous media Label or tagstock that
has no web (space between labels),
notch, or gap to separate each
label/tag, but rather the media is one
long piece of material.
core diameter The inside diameter of the
cardboard core at the center of a roll
of media/ribbon.
cutter A device that can cut each
label/tag immediately after it is
printed.
diagnostics Information about what
printer functions are not working.
This information is used for
troubleshooting problems.
direct thermal printing Printing in which
direct thermal media is used. No
ribbon is used. Instead, the media is
coated with a substance which reacts
to heat to produce an image.
fanfold media Media that comes folded
in a rectangular stack, rather than on a
roll.
font A complete set of alphanumeric
characters in one style of type. Ex:
Times, Helvetica.
ips "inches-per-second" The speed at
which the label or tag is printed.
Zebra offers printers that can print
from 2 ips to 12 ips.
label An adhesive-backed piece of paper,
plastic, or other material on which
information is printed.
label available sensor For printers
equipped with the Peel-Off Option,
this sensor detects a printed label
waiting to be taken or "picked" by the
operator. While it detects this label,
the printer will not print additional
labels. Once the label has been taken,
printing resumes. Also called
“take-label sensor” .
label backing (label liner) The material
on which labels are affixed during
manufacture and which is discarded or
