What is a Dot Matrix Printer?

In order to have a basic appreciation of this we will explain what dot matrix printing is. Dot matrix printing entails the printing of characters on paper by pins (which comprise the print head) which hit a ribbon of ink. Thus the printed characters come out as a series of dots. A dot matrix printer (as known as an impact matrix printer) thus is a printer that works using that mechanism. Typically the print-out comes off dotted-like in appearance which is why the quality can be somewhat lower in comparison to other types of printers. The quality of the print is a function of how many pins the print head has. The number of pins ranges from 9 to 24 (with 24 being the highest quality).

Uses of Dot Matrix Printers

Dot matrix printers are usually used for printouts or forms that have multiple parts. They are also most suited for the printing out of documents whose input data is in the form of a perpetual (or continuous) feed. Examples of such printouts are invoices, payslips, and receipts, just to mention a few. The environments in which dot matrix printers can be used vary from printer to printer. Broadly, the environments span from offices, retail or wholesale outlets, tourism and hospitality facilities to industrial sites. The robustness of their design makes them that versatile and adaptable to even the most adverse environments.

Advantages of Dot Matrix Printers

Not only are dot matrix printers inexpensive to buy (in some cases) they are much cheaper to operate. Note though that buying them cheap is relative since in some cases they can be very expensive to buy. The overall advantage, either way, is how cheap they are to operate. One ribbon can fade after characters numbering millions (as much as 7 million characters actually) have been printed. Low repair and maintenance costs also account for the cheapness of operation.

The dot matrix printers themselves are quite robust and have a significantly long lifespan. This also makes them strong enough to be used in relatively harsh conditions such as construction sites, for instance. This makes them withstand conditions like dust and heat.

Dot matrix printers comfortably handle continuous feeds of paper. This is great advantage when documents being printed are multi-paged. In essence this makes dot matrix printers well-placed to handle high-volumes printing.

One of the greatest advantages of dot matrix printers is their ability to print both carbon and carbonless copies. By this we are referring to the printing of two pieces of paper simultaneously. This is the multiple-part element we mentioned earlier. It is no wonder why they are most suitable for applications such point of sale (POS) or cash registers and way bills (common with courier services companies), amongst others. The running out of ink is not abrupt but rather it is gradual. This makes it easy to for you to notice in good time that the ink needs refilling or the ribbon needs to be replaced.

Disadvantages of Dot Matrix Printers

Dot matrix printers tend to be noisier as compared to the other two types we mentioned earlier. This is borne from the impact nature of their working mechanism. This, however, can be minimized by the inclusion of encasements (padding) in their hardware design.

Over the years, dot matrix printers have been overtaken by inkjet and laser jet printers. This has created a lesser demand for dot matrix printers over the years. The result of that has been a relatively higher price tag for them due to their limited supply. There is the issue of low print quality which stems from dotted-like nature of the print. Tied in to this can be the issue of a much slower print speed in comparison to inkjet or laser jet printers. (These are issues that are relative especially in light of a customer’s intended use).

What Is The Price Of A Dot Matrix Printer?

First of all let us look at non-impact printers e.g. inkjets and laser jets. This is to give some perspective to make comparisons to dot matrix printers which we shall discuss shortly.

The average price range for laser jets is US$200 to US$800. Note, however, that you can get one from as low as US$70 and as high as US$3000. As for inkjets the average price ranges from US$100 to US$500 with the possibility of getting one from as low as US$30 and even as high as US$3000 and beyond.

The operating (printing) costs for inkjet and laser jet printers, in terms of price per page, range from as low as 6 cents to as high as 20 cents per page. The variations depend on whether you are printing in black and white or in colour. The price per page surges when you are dealing with photos or printouts involving high graphics. In such cases the price can be as high as 60 cents per page – for laser jet printers. Generally, laser jets are relatively cheaper to use because they use toner which is longer lasting as opposed to inkjets which use ink.

Now let us look at dot matrix printers:
The printing cost per page of dot matrix is quite low and averages around 2 cents per page. The ribbons for dot matrix printers are also quite cheap – from as low as US$4 you can actually get one. The average price range of dot matrix printers is US$200 to US$600.

Which Dot Matrix Printer Brand Is The Best?

When it comes to the best dot matrix printers, two brands stand out namely, Epson and Oki. Oki is dedicated to creating cost effective, professional in-house printing solutions. Epson prides itself as the world leader of impact printers. It is not that easy to say who the best between these two is because they are quite formidable in terms of what they offer. They are both acclaimed for developing impact printers that are adaptable to harsh environments. They are also both exceptional in the production of dot matrix printers that have longevity (along with low maintenance and operating costs).
