Dot Matrix Printer - A dot matrix printer works by striking an ink ribbon to print tiny and closely spaced dots onto paper to form certain characters and simple images and is excellent for invoices, address labels and carbon copy invoices.
DPI - Dots per inch, used to indicate printing resolutions that are measured both horizontally and vertically. For example, a resolution of 4800 x 1200 dpi means 4800 dots across and 1200 dots down so that there are 5,760,000 dots per square inch in total.
Duplex Printing - A technology allowing printing on both sides of the paper (sometimes referred to as two-sided printing).
Impact Printing - Impact printing creates images and text by striking the print media/paper. Dot matrix printers adopt impact printing technology.
Inkjet Printer - Inkjet printers spray extremely tiny and precise ink droplets to create characters and graphics. Based on color mixing principles, inkjet printers utilize several ink cartridges containing different colors to produce vivid color images, which is why inkjet printers are often applied in picture-intensive printing.
Laser Printer - A laser printer is also non-impact and uses laser to adhere solid toner (typically black powder) instead of spraying liquid ink onto paper to create images. In a laser printer, the drum (looks like a cylinder), laser unit, toner cartridge and fuser are important components for printing.
LPT/ Parallel Port - LPT, also known as Parallel Port, is a type of archived port used in the past by printers; today almost all printers use USB connections.
