Which printer type uses toner cartridges filled with fine powder?

The choice of a laser printer is correct because this type of printer operates using a process that involves toner cartridges filled with fine powdered ink. In a laser printer, the printer uses laser technology to fuse this toner onto paper, creating crisp and clear text and images. The toner is a dry powder that consists of pigments and plastic particles, and when heated, the plastic melts and bonds the toner to the paper.

In contrast, inkjet printers utilize liquid ink stored in cartridges, which is sprayed onto the paper through tiny nozzles to create images and text. A plotter printer is designed for printing vector graphics and uses various ink types or media, while 3D printers create three-dimensional objects by extruding materials like plastic filament or resin, rather than using printing techniques associated with toner. Thus, the defining feature of toner cartridges used in laser printers makes it the correct answer.
