Handheld Inkjet

An inkjet printer is a computer peripheral that produces hard copy by spraying ink onto paper. A typical inkjet printer can produce copy with a resolution of at least 300 dots per inch ( dpi ). Some inkjet printers can make full color hard copies at 600 dpi or more.Technology (How It Works) Inkjet printers spray liquid ink through microscopic nozzles onto paper as pictured below. Laser printers, on the other hand, have a drum unit that fuses (or melts) toner powder onto paper with heat. So, one printer type uses ink, the other uses powder.
