A barcode printer is a computer peripheral for printing barcode [1] labels or tags that can be attached to, or printed directly on, physical objects. Barcode printers are commonly used to label cartons before shipment, or to label retail items with UPCs or EANs .
Whereas a barcode is a machine-readable optical image that contains information specific to the labeled item, the QR code contains the data for a locator, an identifier, and web-tracking. To store data efficiently, QR codes use four standardized modes of encoding: (1) numeric, (2) alphanumeric, (3) byte or binary, and (4) kanji. [5]
A barcode or bar code is a method of representing data in a visual, machine-readable form. Initially, barcodes represented data by varying the widths, spacings and ...
GS1 is a not-for-profit, international organization developing and maintaining its own standards for barcodes and the corresponding issue company prefixes.The best known of these standards is the barcode, a symbol printed on products that can be scanned electronically.
Code 11 is a barcode symbology developed by Intermec in 1977, and it is used primarily in telecommunications. The symbol can encode any length string consisting of the digits 0–9 and the dash character (-). A twelfth code represents the start/stop character, commonly printed as "*".
Codabar is a linear barcode symbology developed in 1972 by Pitney Bowes Corp. [1] It and its variants are also known as Codeabar, Ames Code, NW-7, Monarch, Code 2 of 7, Rationalized Codabar, ANSI/AIM BC3-1995 or USD-4.
By utilizing the barcode's center marker, a scanner can decode an International Article Number (EAN) by scanning one half of the barcode at a time through a helical scan at a 45-degree angle. This method reconstructs the full code from partial scans, useful when the barcode is obscured or damaged.
A barcode reader or barcode scanner is an optical scanner that can read printed barcodes and send the data they contain to computer. [1] Like a flatbed scanner , it consists of a light source, a lens, and a light sensor for translating optical impulses into electrical signals.
