The earliest known form of printing applied to paper was woodblock printing, which appeared prior to 220 AD in China. Later developments in printing technology include the movable type invented by Bi Sheng around 1040 AD and the printing press invented by Johannes Gutenberg in the 15th century.
Throughout the nineteenth century, lithography was primarily a graphic art form and, as such, still holds a high artistic reputation. Lithographs are original artworks of artists and are typically signed, while offset lithographic printing and reproductions do not have a signature.
Gutenberg was a German craftsman and inventor and is best known for his innovative printing press machine, the Gutenberg press, which used a movable form. Up until the 20th century, it remained the standard. Gutenberg made it inexpensive to print.
As the inventor of the printing press, Johannes Gutenberg is usually cited. Indeed, the 15th-century contribution of the German goldsmith to technology was revolutionary, allowing for the mass production of books and the rapid dissemination of knowledge across Europe.

Today, average inkjet printers generally have a 1200 x 1440 dpi resolution. If you're not going to print photos larger than 5 x 7 inches, this is a good enough resolution.
Inks used in industrial printing affect the atmosphere in different ways. During printing, vent fumes are fumes released into the atmosphere by the inks. When inhaled, these fumes can be harmful. After they are discarded, other inks create issues.
