Digital printing is the reproduction of digital images on physical surface, such as common or photographic paper, film, cloth, plastic, etc. It can be differentiated from litho printing in many ways, some of which are; Every impression made onto the paper can be different, as opposed to making several hundred or thousand impressions of the same thing from one set of plates, as in traditional methods. The Ink or Toner does not absorb into the paper, as does conventional Ink, but forms a layer on the surface. It generally requires less waste in terms of chemicals used and paper wasted in set up. Printing at home or in an office is subdivided into:

  • small format (up to ledger size paper sheets), as used in business offices and libraries
  • wide format (up to 3' or 914mm wide rolls of paper), as used in drafting and design establishments.

Some of the more common printing technologies are line printing: 

  • where pre-formed characters are applied to the paper by lines daisy wheel 
  • where pre-formed characters are applied individually dot-matrix
  • which produces arbitrary patterns of dots with an array of printing studs heat transfer
  • like early fax machines or modern receipt printers that apply heat to special paper, which turns black to form the printed image blueprint
  • and related chemical technologies inkjet
  • including bubble-jet
  • where ink is sprayed onto the paper to create the desired image laser where toner consisting primarily of polymer with pigment of the desired colours is melted and applied directly to the paper to create the desired image.

Vendors typically stress the total cost to operate the equipment, involving complex calculations that include all cost factors involved in the operation as well as the capital equipment costs, amortization, etc. For the most part, toner systems beat inkjet in the long run, whereas inkjets are less expensive in the initial purchase price.
