Barcode technology can have applications in many areas. Barcode labels contain data or information of a particular product. These labels are created by barcode printer. Barcode scanners using various technologies read the data present on those labels. Many manufacturers are involved in producing barcodes and Symbol barcode is one among them. Various models of barcodes are created by different types of printers. The most advanced types of barcode printers are thermal printers which are of two types: direct thermal barcode printer and thermal transfer barcode printer. Zebra printers and WASP printers are some of the examples of direct thermal barcode printers.
The above two types of printers differ from each other in their way of functioning. Ink, toner, and ribbon are not used by direct thermal printers. The images are printed directly on treated barcode labels. The labels are first treated with some chemicals. These are heat-sensitive labels and are used for printing by the direct thermal barcode printer. When these labels are passed under thermal printhead of the printer, they get blackened which creates the code.
The design of these printers is simple and hence can be used easily. The cost of these printers is also lesser than ink-jet, laser, and thermal transfer barcode printers. As these printers do not use ink or toner or ribbon, their maintenance is also easy. Direct thermal printing technology is used by most mobile printers.
