Which printer uses powdered toner and heat to create printed images?

• A. Inkjet Printer
• B. Laser Printer
• C. 3D Printer
• D. Impact Printer

Answer: (B)

A Laser Printer uses powdered toner and heat to create printed images. This type of printer utilizes a process called electrophotography, where a laser beam is used to selectively charge areas of a rotating drum. The charged areas attract the powdered toner, which is then transferred to the paper. Heat is applied during the printing process to fuse the toner particles to the paper, resulting in a clear and permanent print.

In contrast, an Inkjet Printer sprays liquid ink onto paper to create images, a 3D Printer builds three-dimensional objects layer by layer, and an Impact Printer uses a hammer mechanism to transfer ink on paper. These different printing technologies highlight the unique characteristics of a Laser Printer that relies specifically on toner and heat.
