Network Printer
Is used in a Laser printer to supply the toner that creates the image on the page.
Toner Cartige
Draws the toner onto the paper
Transfer Roller
Special small containers that store ink.
Ink Cartridge
A thin wire which applies a positive charge to the paper, drawing the negatively charged toner particles to the paper.
Transfer Corona
Fine powder made up of plastic particles bonded to iron particles
Toner
Acts as the writing mechanism of the printer.
Laser
Produces high-quality and high-speed output of both text and graphics.
Laser Printer
A pattern of dots representing what the final product should look like produced by a laser printer.
Raster Image
Enables the printer to insert smaller dots among the characters, smoothing out the jagged curves that are typical of printers that do not use RET.
Resolution Enhancement Technology
Uses a printhead connected toa carriage that contains Ink. A belt and motor move the carriage back and forth so the ink can cover the whole page.
Inkjet Printer
Printers that create an image on paper by physically striking an ink ribbon against the paper’s surface.
