Laser printers use a drum and toner.
Laser printers use a drum and toner in the printing process.
Certain printers do, yes. These types of printers are called Laser Printers. The other type, which uses nozzles and ink cartridges, is called an Ink jet Printer. The drum on a laser printer might not be the kind you're thinking of. It's actually just a big rotating tube that transfers the toner from the toner cartridge to the paper. The toner is particles that have a positive charge, and are attracted to the drum where there is a negative charge (The drum is negatively charged by a laser, thus the name Laser Printer).
During the writing phase, the uniform high charge is discharged only in the places where toner is meant to stick to the drum. This is how the laser printing process that determines when the toner sticks to the drum.
It is during the developing phase of the laser printing process that toner is applied to the latent image on the drum. The toner is a negatively charged mixture of plastic and metal particles.
The purpose of the corona wire on a drum is to create a static charge on the surface of the drum. This charge helps attract toner particles to the drum, allowing for the transfer of the toner onto the paper during the printing process. In essence, the corona wire helps facilitate the printing process by ensuring that the toner adheres properly to the drum and is transferred accurately onto the paper.
The toner hopper is a component in laser printers and copiers that stores and supplies toner powder to the imaging drum during the printing process. It ensures a consistent flow of toner, which is essential for producing high-quality prints. By maintaining an adequate supply of toner, the hopper helps to prevent print quality issues and reduces the frequency of manual refills.

This happens on LASER printers when the drum is damaged. On modern LASER printers the drum is part of the toner cartridge. Replacing the black toner cartridge should solve the problem.
They transfer toner from the drum to the paper.
The magnetic fluid in a LaserJet toner cartridge helps to evenly distribute the toner particles on the drum, which is essential for creating precise and high-quality prints.
