10 Best Dot Matrix Printers

If you run a manufacturing, wholesale, or financial services business where invoices, manuals, reports and other multi-part documents need to be printed regularly, then you understand how important it is to have a reliable, fast, and cost effective printer.

Here, we’ve put together a list of top ten best dot matrix printers as well as some of the factors you need to consider when looking for one. Read on.

Buying Guide

What to Consider When Choosing a Dot-Matrix Printer


Of course you do not want to purchase a printer that will make you break the bank. When opting for a dot matrix printer, consider how much you are willing to spend. While on budget, also consider the kind of tasks you need to complete more often. Is it invoice, receipt, or spreadsheet printing? If you’ve got a high demand for this, it’s vital to consider a multifunctional printer. However, it’s prudent to remember that not all expensive models deliver as advertised.

Print quality

Unlike other printers, the dot matrix printing quality is determined by the number of pins. The number of pins vary from 9 to 24. The higher the number of pins the better the print quality.


Typically, dot matrix printers vary when it comes to the number of characters printed per second. This can be anything between 50cps and 5000cps. If you require high speeds, then select one with higher speed settings. The good thing, however, is that most dot matrix printers come with a control setting that allows you to adjust the speeds.

Auto cutter

When shopping for a dot matrix printer, check whether it has a tear bar or an auto cutter. An auto cutter may be a little convenient because it will not only help save you time but also make work easier.


Dot matrix printers are mostly suited for busy work environments. As such, they need to be incredibly durable and strong.

Energy efficiency

Dot matrix printers are workhorses that can run for hours without stopping. As such, it’s important to buy a machine that’s energy efficient and that will reduce the amount of paper used. This will not only help conserve the environment but also result in significant savings overtime.
