Question

Which printer uses toner powder to print?

• A. Dot Matrix Printer
• B. Laser Printer
• C. Inkjet Printer
• D. Thermal Printer

Hint:

Laser printers use toner powder and heat to produce high-quality prints—unlike inkjet or thermal printers.

Answer 1

The Correct Option is B

Step 1: Understanding toner-based printing
Toner powder is a dry, powdered substance used in laser printing to form printed text and images on paper.


Step 2: Function of a laser printer
Laser printers use a laser beam to produce an image on a drum.
The drum then attracts toner, which is fused onto the paper using heat.


Step 3: Elimination of incorrect options
Dot Matrix Printer uses ink-soaked ribbons.
Inkjet Printer sprays liquid ink.
Thermal Printer uses heat-sensitive paper, not toner.


Step 4: Conclusion
Only the Laser Printer uses toner powder, making option (2) correct.
