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 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 is 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.
