“Printing is a process for reproducing text and images, typically with ink on paper using a printing press. It is often carried out as a large-scale industrial process, and is an essential part of publishing and transaction printing.

The development of printing was preceded by the use of cylinder seals in Mesopotamia developed in 3500 B.C., and other related stamp seals. The earliest form of printing was woodblock printing, with existing examples from China dating to before 220 A.D.[1] and Egypt to the fourth century. Later developments in printing include the movable type, first developed by Bi Sheng in China,[2] and the printing press, a more efficient printing process for western languages with their more limited alphabets, developed by Johannes Gutenberg in the fifteenth century.”

Some of the more common printing technologies are:

blueprint – and related chemical technologies

daisy wheel – where pre-formed characters are applied individually

dot-matrix – which produces arbitrary patterns of dots with an array of printing studs

line printing – where formed characters are applied to the paper by lines

heat transfer – such as early fax machines or modern receipt printers that apply heat to special paper, which turns black to form the printed image

inkjet – including bubble-jet, where ink is sprayed onto the paper to create the desired image

electrophotography – where toner is attracted to a charged image and then developed

laser – a type of xerography where the charged image is written pixel by pixel using a laser

solid ink printer – where cubes of ink are melted to make ink or liquid toner”
