Dot matrix printing or impact matrix printing is a type of computer printing which uses a print head that moves back-and-forth, or in an up-and-down motion, on the page and prints by impact, striking an ink-soaked cloth ribbon against the paper. Dot matrix printer prints character in only one stroke.

Understanding the Printing Technology
When discussing how different printers produce characters, it's essential to recognize the distinct mechanisms involved in their operation.
Dot Matrix Printer
- Character Formation: Dot matrix printers create characters by striking an ink-soaked ribbon against the paper using a matrix of pins. Each pin represents a dot, and by activating specific pins, the printer can form letters and shapes.
- Single Stroke Printing: The reason a character is printed in one stroke is that the matrix can produce the entire character in one pass. This allows for a more continuous and efficient printing process, especially for simple text.
Comparison with Other Printers
- Laser Printer:
- Utilizes a laser beam to create an image on a drum, which then transfers toner to the paper. While efficient, it does not print characters in one stroke but rather layers the image gradually.
- Line Printer:
- Prints one line at a time, often using a series of hammers or chains. Although faster than dot matrix printers for bulk printing, it does not produce characters in a single stroke but rather line by line.
- Plotter:
- Primarily used for large-scale graphics and diagrams. It uses a pen or other instruments to draw images, which is fundamentally different from character printing.
Conclusion
In summary, the dot matrix printer is unique in its ability to produce characters in a single stroke due to its design based on a pin matrix, making it a suitable choice for certain printing tasks, especially in environments requiring multi-part forms or simple text outputs.
