Bar Code Label Printers: What Are They And How Do They Work?
Bar code label printers are highly specialized, in that they do only one thing: print bar codes. They're generally smaller than other kinds of printers, and are used a lot in department stores and warehouses.
Any printer, however, can print bar codes. For this purpose, laser printers are a lot better than inkjet, as the clarity is higher and the production is faster. Even so, regular printers are still too slow to be considered permanent bar code printers. For this, you need a thermal or a thermal transfer printer.
This kind of printer has a thermal head that applies direct heat on a paper that is specific to the task. This heat darkens the area, producing high quality images very quickly. Thermal head printers are ideal when you need a job done fast, like in department stores where inventory has to move.
A major problem with thermal printers, however is that since all this heat is being generated, the heads do wear out occasionally and need to be replaced.
Bar code label printers need to be cleaned regularly. This is especially true of the ribbon and the print head. In warehouses where dust is sometimes a huge problem, specks can cause the bar codes to be distorted. Printers that are using ANSI software should have their outputs continually checked to avoid system malfunctions.
Almost all printers today are compatible with Windows drivers. You can connect them to computers to find out what kind of output they would produce. You can find software to design your own labels. Some printers, however, are not compatible with other computers. Instead, numerical code must be fed into them to generate the bar code label that you need.
Mostly, barcode label printers print on labels specifically designed for that purpose. Many can, however, print on various fabrics. Headbands, T-shirts, and other materials sometimes can be seen with a bar code.
Although bar codes are usually black for practical purposes, they can actually be printed in several different colors. The reason black is preferred is contrast. Unless there is sufficient contrast, a scanner might have difficulty reading the code.
Most thermal printers today employ features that make sure no counterfeit coding takes place. These printers print what are known as "smart labels." Smart labels contain radio frequency identification chips in the label media itself. These smart features ensure that any loopholes in barcode printing are plugged, providing a guarantee of authentication.
