6. Impact Printers Characteristics: Printing Method: Uses a print head that physically strikes an ink ribbon to imprint characters on paper. Speed: Generally slower compared to modern non-impact printers. Noise: Produces significant noise due to mechanical impact. Cost: Relatively inexpensive but requires regular maintenance. Usage: Commonly used in banks, ticket counters, billing systems, and industrial applications. Characteristics: Printing Method: Uses a print head that physically strikes an ink ribbon to imprint characters on paper. Speed: Generally slower compared to modern non-impact printers. Noise: Produces significant noise due to mechanical impact. Cost: Relatively inexpensive but requires regular maintenance. Usage: Commonly used in banks, ticket counters, billing systems, and industrial applications. Impact printers are a type of printer that prints by striking an inked ribbon against paper, similar to a typewriter. These printers use mechanical components to transfer ink, making them noisier than non-impact printers.

7. A dot matrix printer is an impact printer that prints characters and images by striking a series of tiny pins against an inked ribbon to form dots on paper Dot-matrix Printers IMPACT PRINTERS

8. Dot Matrix Printer The printer has a print head with multiple pins arranged in a grid. These pins strike an inked ribbon, which transfers ink onto the paper in the form of tiny dots. The combination of these dots forms characters, numbers, or images. The print head moves horizontally while the paper moves vertically for continuous printing. Working Principle of

13. A daisy wheel printer is an impact printer that prints characters by striking a pre-formed character wheel (daisy wheel) against an inked ribbon, similar to a typewriter. DAISY WHEEL IMPACT PRINTERS

14. DAISY WHEEL PRINTER The Daisy Wheel is a disk with spokes resembling a flower. Each spoke has a character molded into it. The wheel rotates to bring the correct character to the print head position. The hammer strikes the wheel to imprint the character on paper. WORKING PRINCIPLES OF :
