Printing is the process of copying text and images using a master form or template. The earliest form of printing applied to paper was woodblock printing, which appeared in China before 220 AD. Later developments in printing technology include the invention of movable type printing by Bi Sheng around 1040 AD and the invention of the printing press by Johannes Gutenberg in the 15th century. Printing technology played a key role in the development of the Renaissance and the Scientific Revolution, laying the material foundation for the modern knowledge economy and the dissemination of knowledge to the masses.
Inkjet printing technology
A type of computer printing that recreates a digital image by ejecting droplets of ink onto paper, plastic, or other substrates. Inkjet printers are the most commonly used type of printer, ranging from small, inexpensive consumer models to expensive professional machines.

Continuous inkjet (CIJ)
Continuous inkjet (CIJ) methods are used commercially for the marking and coding of products and packaging. In 1867, Lord Kelvin patented a siphon recorder, which used an ink jet nozzle deflected by a magnetic coil to record telegraph signals as a continuous track on paper.
Drop-on-demand (DOD) is divided into thermal DOD and piezoelectric DOD.
Thermal inkjet printing initiates the ejection of ink droplets by superheating a small portion of solvent-based ink. Heating performed by small resistors or other heating elements causes bubbles to form and eject ink droplets. The inks involved are usually water-based and use pigments or dyes as colorants. The ink must have volatile components to form bubbles; otherwise, droplet ejection will not occur. Since no special materials are required, printheads are generally cheaper to produce than other inkjet technologies.
Piezo printing methods contract the ink chamber by energizing a piezoelectric substance that moves when energized. A drop of ink is ejected onto the print medium. Piezo printing has yet to be adopted by many mainstream photo printer manufacturers. However, it finds more use in industrial printing and specialized large format printers, including special surface printing that can use a wider variety of ink bases.
4 advantages of inkjet printing
Inkjet printers have many advantages over earlier consumer-oriented color printers.
1. They run quieter than impact dot matrix or daisy wheel printers.
2. They can print finer, smoother details at higher resolutions. Consumer-grade inkjet printers with photo-quality printing capabilities are everywhere.
3. Compared to technologies such as thermal wax, dye sublimation, and laser printing, inkjet technology has the advantage of requiring little warm-up time and generally lower cost.
4. Certain types of industrial inkjet printers are now capable of printing at very high speeds, in wide format, or for a variety of industrial applications ranging from signage, textiles, ceramics, and 3D printing to biomedical applications and conductive circuits.
