Printers

Definition

Printers are information output devices that create a hard copy of processed data or information on paper. They play a crucial role in producing physical documents, images, and graphics from digital files.

Types of Printers

1. Impact Printers

   • Description: Impact printers operate by physically striking an ink ribbon against paper to print characters. They use a print head or hammer that makes contact with the paper to transfer ink.

   • Examples:

     • Dot Matrix Printer: Uses a matrix of pins to create characters by striking an inked ribbon against the paper.
     • Daisy Wheel Printer: Utilizes a wheel with raised characters that strikes the ribbon to print text, similar to a typewriter.
     • Line Printer: Prints an entire line of text at once using a series of print heads, making it suitable for high-speed printing.
     • Chain Printer: Uses a chain of characters that moves across the paper, printing multiple characters in one pass.

   • Characteristics:

     • Extremely low consumable costs, making them cost-effective for high-volume printing.
     • Fairly noisy during operation due to the mechanical striking action.
     • Ideal for large-scale printing tasks because of their affordability.
     • Requires physical contact with the paper to create an image.

2. Non-Impact Printers

   • Description: Non-impact printers create images and text without physically striking the paper. They are often referred to as page printers because they can print an entire page at once.

   • Examples:

     • Laser Printer: Uses a laser beam to transfer toner onto paper, producing high-quality prints at fast speeds.
     • Inkjet Printer: Sprays tiny droplets of liquid ink onto the paper to create images and text, offering vibrant color reproduction.

   • Characteristics:

     • Quicker printing speeds compared to impact printers.
     • Operate quietly, as there is no mechanical striking involved.
     • Produce superior print quality, with finer details and smoother edges.
     • Support a wide range of fonts and character sizes, enhancing versatility in printing.
