Bar codes enhance data management considerably, and virtually every company is using quite innovative versions of the technology now. Bar codes accelerate information collection considerably by keeping substantial quantities of data in little black lines which may be readily machine-read.
Bar code label printers are usually the most frequent scatter matrix, laser, laser and inkjet and thermal printers. Dot matrix printers are among the earliest printers used for printing bar codes. In such printers, the traces are constructed dot-by-dot as a solenoid-driven needle strikes an ink ribbon, moving the ink into the paper.
Nevertheless, they are acceptable for just high-speed bar code printing (which is also known as “การพิมพ์บาร์โค้ด” in Thai language). Ink jet clogging, restricted recorder resolution, “bleeding” ink, and inferior contrasts are a few of the disadvantages.
Laser printers are rather good so much as the quality of the printing is worried. They have quite great resolutions and may scan very nicely. But, they can’t efficiently print labels that are smaller. The glue on the labels needs to be great enough to take the heat and strain from the printer since most tag adhesive often melt. Thermal printers such as bar coding are two kinds: direct printing and thermal transport.
Bar code printers need to be examined on the basis of: quality of this printing, readability, first installation price, speed, longterm upkeep cost, materials squander. Every one of these printers has distinct outcomes. Thermal label printers score well on all facets except for substance waste.
They are most appropriate for programs which have variable data areas, point-of application programs, varying tag sizes, scalable and graphical text fonts, and high-definition bar codes.
