A dot matrix printer is a printer whose print resolution is still very low. In fact, dot matrix printers tend to make loud noises when printing. In addition, the quality of the resulting image from the printer is not good. This can be seen from the results of the image that looks like interconnected dots.
Understanding Dot Matrix Printers and Explanations
In general, dot matrix printers also only have one color, namely black. This type of printer is classified as a type of printer that prints to paper in a “direct” way. That is, the printer directly “taps” the ink ribbon opposite the paper. The way a dot matrix printer works is like a typewriter, which can also be used to print several papers at once, with carbon paper inserted in each page of the paper.
The head of this printer consists of 7 or 9 or 24 needles arranged vertically and forming a column. When working, the needle on this printer will form character images through the friction of the needle on the carbon and paper.
When the head-printer moves from left to right while touching the paper, the letters that have been patterned in a needle arrangement will immediately appear. This letter pattern is then received by a carbon tape behind which there is paper, and letter by letter printing occurs. Each character that is formed will cause a unique pattern consisting of various points in the dimensions of a matrix. Types of this printer there are color and non color. For color printers, special ribbons are used that have 4 colors, namely black, blue, red and yellow.
This printer has a much cheaper price when compared to toner for laser jet and ink jet type printers. In addition, the types are very varied. Some are non-colored and some are color. For color printers, special ribbons (carbon/ribbon) are used which have 4 colors, namely black, blue, red and yellow. In fact, this printer is also capable of printing multiple copies at once with a wide paper size. However, this printer also still has drawbacks.
One of them is the print resolution is still very low and the printer sound is very loud when printing. In fact, because the print quality is still very low, the printed image will look like interconnected dots. In addition, this printer is also low in DPI and PPM. Finally, the resulting color does not vary and the motion is arguably very slow.
That’s the information about Understanding Dot Matrix Printers and their explanations, hopefully it’s useful.
