Bar code label printers are generally the most common dot matrix, laser, and ink jet and thermal printers. Dot matrix printers are one of the oldest printers used for printing bar codes. In these printers, the lines are built dot-by-dot as a solenoid-driven needle strikes an ink ribbon, transferring the ink to the paper. These printers are inexpensive, can print any form and are easily accessible. However, the quality dot matrix printer is unacceptable today. Ink jet printers are one of the most commonly used printers, especially for high-speed applications. They can also be used to print directly onto a carton where a label has already been affixed.
However, they are suitable for only high-speed printing and may not be very cost-effective for small-scale bar code printing operations. Ink jet clogging, limited barcode resolution, “bleeding” ink, and poor contrasts are some of the disadvantages. Laser printers are quite good as … Read the rest
