Once of the most revolutionary inventions of all time was the movable press created by Johann Gutenberg. This directly lead to the Reformation, the Renaissance and the Scientific Revolution. The basic form of printing, whether with industrial printing machines or a typewriter has not changed much in the next 600 years after Gutenberg.
The next evolutionary step in printing came with digital printing. Most advanced digital printing techniques make use of either a laser engine or a inkjet/bubblejet. In both instances, there is no type which comes in contact with the page. Rather, the whole page is re-created from the printer’s memory.
Digital printing is used in many applications, from creating typeset, lithographs, silk-screens, direct to t-shirt printing, as well as printing correspondence on paper. The applications are endless and only limited by the needs of the person involved. If there is a requirement, there is a digital printing method or technique which can do it. You can find toner and other digital printing needs at leading online retailers.
