Printer Ribbons for Dot Matrix PrintersIt may seem old fashioned but the most cost effective way of printing documents would be a dot matrix printer which would use continuous paper.It’s a bit noisy and perhaps slower than an ink jet printer or a laser printer but you can read what is printed, and the cost of a ribbon would be just a few pounds.If you should require multiple  copies of the same document it could be quicker, depending on the speed of the printer itself.The main use today would be for the printing of multi-part invoices or payslips. For example you could print a Sage or Iris security payslip which consists of an employers copy and a pay-slip in its  own envelope in a fraction of the time it would take to produce a laser payslip fold it into shape then put it into an envelope to hand to the employee.The added advantage is security as the only persons able to view the information would be the wages clerk and the employeeThe principle of a dot matrix printer is impact printing so that the image using carbonized paper goes through to the next sheet. Most Epson, Panasonic, Oki and Tally printers are capable of printing between 4 and six sheets at a time
