Impact printers were the original computer printers – these included models such as daisy wheel, dot matrix and line printers. As print technologies developed, and printing needs became more complex, the industry introduced new non-impact models that changed the way that printers worked. These included inkjets, laser and thermal products. The primary difference between impact and non-impact printers is the print mechanism itself, but there are also differences in quality, features, usage and cost. Writer Bio
