Line printers are high-speed printing devices that produce entire lines of text at once, rather than printing one character at a time. They are commonly used in environments where large volumes of printing are required, such as in data centers or for generating reports. Line printers can be either impact or non-impact types, with impact printers using a mechanism similar to a typewriter to strike inked ribbons against paper. These printers are known for their efficiency and ability to handle continuous forms of paper, making them suitable for printing invoices, payroll, and other bulk documents. While they have largely been replaced by laser printers and inkjet printers in many applications, line printers are still valued for their speed and reliability in specific industrial settings.
