Alphanumeric — Indicating letters, numerals, and characters such as punctuation marks.
Backfeed — When the print engine pulls the media and ribbon (if used) backward into the
print engine so that the beginning of the label to be printed is properly positioned behind the
printhead. Backfeed occurs when operating the print engine in Tear-Off and Applicator modes.

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.

start-of-label indication for the print engine. (See continuous media.)
start-of-label indication for the print engine. (See continuous media.)
Calibration (of a print engine) — A process in which the print engine determines some basic
information needed to print accurately with a particular media and ribbon combination. To do
this, the print engine feeds some media and ribbon (if used) through the print engine 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.

Configuration — The print engine configuration is a group of operating parameters specific
to the print engine application. Some parameters are user selectable, while others are
dependent on the installed options and mode of operation. Parameters may be switch
selectable, front panel programmable or downloaded as ZPL II commands. A configuration
label listing all the current print engine parameters may be printed for reference.
