line printer - Computer Definition
An impact printer that prints one line at a time. The two surviving line printer technologies are band printers and line matrix printers. Line printers are still widely used in datacenters and in industrial environments and can print multipart forms at a very rapid rate. For example, a 1,000 lpm line printer printing on three-part forms is the equivalent of a 50 ppm laser printer. See band printer, line matrix printer and printer.
