Three-dimensional printing is a method of converting a virtual 3D model into a physical object. 3D printing is a category of rapid prototyping technology. 3D printers typically work by 'printing' successive layers on top of the previous to build up a three dimensional object. 3D printers are generally faster, more affordable and easier to use ...

Amos Edward Joel Jr. (1918–2008) U.S. – electrical engineer, known for several contributions and over seventy patents related to telecommunications switching systems
The history of computing hardware spans the developments from early devices used for simple calculations to today's complex computers, encompassing advancements in both analog and digital technology. The first aids to computation were purely mechanical devices which required the operator to set up the initial values of an elementary arithmetic ...
The controller and scanner were common to both models, but the Model 90 used a different print engine based on one developed for the previously announced Xerox 4090 printer. The original DocuTech Production Publisher was capable of scanning and then printing black-and-white pages at up to 135 pages per minutes (for letter or A4 sizes) with an ...
Letterpress printing was the normal form of printing text from its invention by Johannes Gutenberg in the mid-15th century and remained in wide use for books and other uses until the second half of the 20th century, when offset printing was developed. More recently, letterpress printing has seen a revival in an artisanal form.
A virtual printer is a piece of computer software whose user interface and API resembles that of a printer driver, but which is not connected with a physical computer printer. A virtual printer can be used to create a file which is an image of the data which would be printed, for archival purposes or as input to another program, for example to ...
This crude method of printing took root in other parts of the world, but didn't change much until the 1100s. Then, around 1440, German inventor Johannes Gutenberg invented and developed movable type, where individual letters, usually engraved into lead, could be rearranged for new word configurations with ease. This change revolutionized the ...
Word processors evolved dramatically once they became software programs rather than dedicated machines. They can usefully be distinguished from text editors, the category of software they evolved from. [5] [6] A text editor is a program that is used for typing, copying, pasting, and printing text (a single character, or strings of characters).
