GLOSSARIES Bar code
A code which represents alphanumeric characters
by using a series of black and white stripes in
different widths. Bar codes are used in various
industrial fields: Manufacturing, Hospitals,
Libraries, Retail, Transportation, Warehousing, etc.
Reading bar codes is a fast and accurate means of
capturing data while keyboard entry tends to be
slow and inaccurate.
Batch mode
Issue mode that continuously prints media until the
specified number of media has been printed.
Black mark
A mark printed on the media so that the printer can
maintain a constant print position by detecting this
mark.
Black mark sensor
A reflective sensor which detects the difference of
potential between the black mark and print area to
find the print start position.
DPI
Dot Per Inch
The unit used to express print density.
Feed gap sensor
A transmissive sensor which detects the difference
of potential between the gap between labels and
the label to find the print position of the label.
Font
A complete set of alphanumeric characters in one
style of type. E.g. Helvetica, Courier, Times, etc.
Gap
Clearance between labels
IPS
Inch per second
The unit used to express print speed.
Label
A type of media with adhesive backing.
Media
Material on which data is printed by the printer.
Label, tag paper, fanfold paper, perforated paper,
etc.
Pre-printed media
A type of media on which characters, logos, and
other designs have been already printed.
Print head
A print head that prints on the thermal media
which reacts to heat by supplying the thermal
elements with current causing the thermal element
to heat up.
Print head element
The thermal print head consists of a single line of
tiny resistive elements and when current is allowed
to flow through each element it heats up causing a
small dot to be burned onto thermal paper.
Printing speed
The speed at which printing occurs. This speed is
expressed in units of ips (inches per second).
Resolution
The degree of detail to which an image can be
duplicated. The minimum unit of divided image is
called a pixel. As the resolution becomes higher,
the number of pixels increased, resulting in more
detailed image.
Tag
A type of media having no adhesive backing but
black marks to indicate the print area. Usually tags
are made of cardboard or other durable material.
Thermal direct printing
A printing method using no ribbon, but thermal
media which reacts to heat. The thermal print head
heats the thermal media directly, causing print
image to be printed on the media.
