Concept:Different printer technologies use different materials; toner is the dry powder specifically used by laser printers.
Explanation:Laser printers use a dry, electrically charged powder called toner.
The printer transfers the toner onto the paper and then applies heat and pressure to fuse it permanently.
This process produces sharp, smudge-resistant text and graphics.
Inkjet printers, on the other hand, spray liquid ink onto the page.
Thermal printers use heat-sensitive paper or thermal ribbons.
Dot matrix printers create characters by striking an ink ribbon with small pins.
Therefore, the document printer that relies on toner is the laser jet printer.
Answer:B. Laser jet printer
