Direct thermal printer A printer that prints onto special thermally coated paper. The thermal head has direct contact with the thermal paper, which cause the item to be printed.
DPI (Dots Per Inch) Dpi refers to the quality of the inkjet printer and is directly related to the density of the printhead. An image is produced by a series of dots that appear on the label. The greater the number of dots on the label means there will be higher print quality or resolution.
Hybrid printer a multifunction printer using combined thermal and dot-matrix heads
Impact printer a printer which relies on physical pressure, applied by a printhead, between paper and inksource (ribbon) to produce characters (essentially dot-matrix type printers)

Receipt printer For printing receipts, a receipt printer is necessary for all point of sale systems. There are many choices of printers available, such as thermal printers or impact printer, and many different features are offered, such as automatic paper cutters, and parallel or serial ports.
Thermal transfer printer A printer that uses thermal ribbons for printing. The thermal head heats up the thermal ribbon and then transfers the image on to the paper.
Auto-discrimination The ability of a barcode decoder to automatically determine what type of barcode is being scanned.
Bar Code A technology that uses white spaces and black bars to represent encoded information. This encoded information can then be read with an optical device that converts the bars and spaces into an electrical signal, which is then decoded into the original characters.

Character Set Characters available for encodation in a particular bar code type. Not all bar code types can encode the entire ASCII character set.
Decoder As part of a bar code reading system, the electronics that process the signals from the scanner, interpret the signals into meaningful data, and control the interface to other devices.
Depth of Field The distance between the maximum and minimum surface in which a scanner is capable of reading bar codes of a specified X dimension.
First Read Rate A bar code verification term. The ratio of the number of successful reads to the number of attempts. Commonly expressed as a percentage. Abbreviated as FRR.
Laser Light Amplification by the Stimulated Emission of Radiation. A focused light source (as opposed to LEDs used in wands and CCD readers) used in fixed, moving beam, and handheld scanners.
LED Light-emitting diode. The light source often used in light pens.
Light pen Also known as a wand. A scanning device which is used as a hand held bar code reader. Requires direct contact with the printed bar code field.
Moving beam scanner A device where scanning is achieved by mechanically moving a light beam through the bars of a bar code field.
Magnetic Stripe Reader (MSR) A device that can read and decode the magnetic stripes on the backs of credit cards, etc.
Resolution The narrowest element dimension which can be recognized by a particular scanning device or printed with a particular device or method.
Omnidirectional When the barcode can be presented to the scanner and read in any orientation.
Orientation The alignment of the symbol's scan path. Two possible orientations are horizontal with vertical bars and spaces (picket fence) and vertical with horizontal bars and spaces (ladder). An omnidirectional scanner can read a barcode in any orientation.
Scanner An electro/optical device that converts the bars and spaces of a bar code field into electrical signals.
Symbology A set of rules defining the encoding of conventional data into a barcode form.
