    Printers

    • Dot Matrix Printers:
    • Used for printing duplicate copies quickly and cheaply
    • Limited to situations where carbon copies are needed and quality is not important
    • Low printing quality
    • Low purchase cost and running costs
    • Can print fairly quickly
    • Robust and can operate in harsh environments
    • Can produce multiple copies using self-carbonating paper
    • Ink Jet Printers:
    • Popular choice for home and school use
    • Ink cartridges can be expensive, leading to high running costs
    • Relatively inexpensive
    • Produce high-quality black and white or color printing
    • Slow speed compared to laser printers
    • Laser Printers:
    • Commonly used for fast, high-quality printing
    • Non-color laser printers are more expensive than ink-jet printers
    • Color laser printers are more expensive but offer high-quality output
    • Quiet and fast, producing high-quality printouts
    • Low running costs due to long-lasting toner cartridges

    Plotters

    • Devices that draw pictures on paper based on computer commands
    • Different from printers, as they draw lines using a pen
    • Can produce continuous lines, unlike printers which simulate lines with dots
    • Multicolour plotters use different colored pens to draw different colors
    • Often used in science and engineering applications for drawing building plans, printer circuit boards, and machine parts
    • Fast and accurate, but relatively expensive compared to printers
    • Can produce large printouts, up to the size of a small room

    Headphones

    • Provide sound output from the computer
    • Similar to speakers, but worn on the ears, allowing only one person to hear the output
