Glossary
alphanumeric Indicating letters, numerals, and characters such as punctuation marks.
backfeed 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
operating the printer in Tear-Off and Applicator modes.
barcode 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.
black mark media Media with registration marks found on the
underside of the print media that act as start-of-label indications for
the printer. The reflective media sensor is typically the best choice for
use with black mark media.
Contrast this with continuous media or gap/notch media.
calibration (of a printer) A process in which the printer determines some basic information needed to print
accurately with a particular media and 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, and (if using non-continuous media) the length of individual labels or tags.
collection method Select a media collection method that is compatible with your printer options. Selections
include tear-off, peel-off, cutter, and rewind. The basic media and ribbon loading instructions are the same
for all collection methods with some additional steps necessary for using any media collection options.
configuration The printer configuration is a group of operating parameters specific to the printer
application. Some parameters are user selectable, while others are dependent on the installed options and
mode of operation. Parameters may be switch selectable, control panel programmable, or downloaded as
ZPL II commands. A configuration label listing all the current printer parameters may be printed for
reference.
continuous media Label or tag-stock media that does not have
gaps, holes, notches, or black marks to indicate label separations.
The media is one long piece of material wound into a roll. This allows
the image to be printed anywhere on the label. Sometimes a cutter is
used to cut apart individual labels or receipts.
Contrast this with black mark media or gap/notch media.
core diameter The inside diameter of the cardboard core at the center of a roll of media or ribbon.
