Which of the following statements are correct? A. Laser printers use dry ink B. Unlike dot matrix and inkjet printers, laser printers do not use ink when producing a document C. Laser printers use the property of static electricity D.

A printer is an electronic device that accepts text files or images from a computer and prints them on paper or film.
Key Points
- A printer is essentially an output device that prints a tangible copy of electronic data stored in a computer or other device.
- There are many various types of printers such as Inkjet Printers, Laser Printers, 3D Printers, LED Printers, Solid Ink Printers, Dot Matrix Printers, etc.
- Inkjet and Laser printers are the most used printer.
- Laser printing is a type of digital printing that uses electrostatics.
- A laser printer does not require ink but it uses toner, which is made up of plastic and iron particles that are heated and melted to the paper by a fuser unit.
- The high voltages inside the printer can cause ozone gas and tiny toner particulates in the air.
Thus, laser printers use toner which will not dry out the same way an ink cartridge does., laser printers use the property of static electricity and laser printers produce ozone gas and tiny toner particulates in the air.
Hence A, C, and D only are correct in the context of Laser printers.
