type, for printing printing, means of producing reproductions of written material or images in multiple copies. There are four traditional types of printing: relief printing (with which this article is mainly concerned), intaglio, lithography, and screen process printing.

, was invented in China (c.1040), using woodblocks. Related devices, such as seals and stamps for making impressions in clay, had been used in ancient times in Babylon and elsewhere. Movable type made from metal molds were developed in Korea as early as the beginning of the 13th cent. However, there is no evidence that the European invention of movable type attributed to Johann Gutenberg Gutenberg, Johann , c.1397–1468, German inventor and printer, long credited with the invention of a method of printing from movable type, including the use of metal molds and alloys, a special press, and oil-based inks: a method that, with refinements and

 was influenced by Eastern developments. The first dated printing from movable type in Europe is a papal indulgence, printed at Mainz in 1454. The first dated book printed from movable type was a Psalter printed by Fust Fust or Faust, Johann , d. 1466?, printer at Mainz. Johann Gutenberg borrowed substantial sums of money from Fust, a goldsmith, lawyer, and money lender.

, completed at Mainz not later than 1455, is believed to be the first book printed in Europe from movable type. The type used in these beginnings of European printing was of the kind known as black letter or Gothic, represented now by such types as Old English and German. The forms of the letters were derived from popular handwriting styles. Other styles suggested the letter forms of roman and italic type. Roman type was used by several printers before Nicolas Jenson Jenson or Janson, Nicolas , d. c.1480, Venetian printer, b. France. Jenson studied printing with Gutenberg at Mainz for three years.

 so improved it as to ensure its triumph as the standard type. Italic type was first used by Aldus Manutius Aldus Manutius or Aldo Manuzio , 1450–1515, Venetian printer. He was educated as a humanistic scholar and became tutor to several of the great ducal families.

, who also introduced small capitals. Roman type is of two basic sorts, old style and modern. The modern type emphasizes the contrast between light and heavy lines and has conspicuous level serifs; the old style type keeps its lines of nearly the same weight and has inconspicuous serifs, some of them sloping. Qualities of old style and modern types are often combined. Into the mid-20th cent. type characters were usually made by pouring metal into previously cut matrices and, less frequently, by processes using plastics and other synthetic materials. Computerization of type design and photomechanical printing techniques have almost entirely replaced metal type. Famous designers of types include, in addition to those named above, Geofroy Tory Tory, Geofroy , c.1480–1533, Parisian printer, typographer, and author, b. Bourges.

type
(1) In data or text entry, to press the keys on the keyboard.

(2) In programming, a category of variable that is determined by the kind of data stored in it. For example, integer, floating point, string, logical, date and binary are common data types.

(3) (Type) In DOS and OS/2, a command that displays the contents of a text file. See DOS Type.

Try Typing on These Keys!
This was high tech in the 1890s, but it wasn't so easy tapping these keys. Notice there's no QWERTY keyboard. Considered the first portable typewriter, George Blickensderfer created this beauty in 1893. (Equipment courtesy of Dorothy Hearn.)

type
1. Biology
a. the taxonomic group the characteristics of which are used for defining the next highest group, for example Rattus norvegicus (brown rat) is the type species of the rat genus Rattus
b. (as modifier): a type genus
2. Logic a class of expressions or of the entities they represent that can all enter into the same syntactic relations. The theory of types was advanced by Bertrand Russell to avoid the liar paradox, Russell's paradox, etc.
3. Philosophy a universal. If a sentence always has the same meaning whenever it is used, the meaning is said to be a property of the sentence-type
4. Chiefly Christian theol a figure, episode, or symbolic factor resembling some future reality in such a way as to foreshadow or prefigure it

type [′tīp]
(graphic arts)
The relief or plane characters used to generate printed characters of various styles and sizes.
(systematics)
A specimen on which a species or subspecies is based.

(theory, programming)type - (Or "data type") A set of values from which a variable, constant, function, or other expression may take its value. A type is a classification of data that tells the compiler or interpreter how the programmer intends to use it. For example, the process and result of adding two variables differs greatly according to whether they are integers, floating point numbers, or strings.

Types supported by most programming languages include integers (usually limited to some range so they will fit in one word of storage), Booleans, floating point numbers, and characters. Strings are also common, and are represented as lists of characters in some languages.

If s and t are types, then so is s -> t, the type of functions from s to t; that is, give them a term of type s, functions of type s -> t will return a term of type t.

Some types are primitive - built-in to the language, with no visible internal structure - e.g. Boolean; others are composite - constructed from one or more other types (of either kind) - e.g. lists, arrays, structures, unions. Object-oriented programming extends this with classes which encapsulate both the structure of a type and the operations that can be performed on it.

Some languages provide strong typing, others allow implicit type conversion and/or explicit type conversion.

Type 

a rectangular piece of metal, plastic, or wood with a raised image of a letter or character on one side. The raised or recessed image serves to reproduce letters and characters by printing, in which the face is covered with ink and an impression is made on paper. Metal type is the most common; it is cast from printing alloy. The parts of a piece of type (see Figure 1) are the body (a), beard (b), and face (c); the dimensions of the type are defined by the point size (d), width (e), and height to paper (f). The last dimension is constant for all kinds of type.

Type 

an element with which a particular taxon is always associated. The type of a species or an intraspecific taxon is usually a single specimen of a plant or animal or, less commonly, several specimens viewed together on one herbarium sheet or in one laboratory preparation. Sometimes a drawing serves as a type. The type of the plant species Companula aldanensis is a specimen collected by the Russian botanist V. S. Korzhevin on Aug. 6, 1928, on the bank of the Aldan River in Siberia; the specimen is preserved in Leningrad at the herbarium of the V. L. Komarov Botanical Institute of the Academy of Sciences of the USSR.

The term “type” is also used as a designation for a lower taxonomic category that is selected as a standard of reference for a higher category. The type of a genus or of a taxon between a genus or species (for example, a subgenus or section) is a particular species. For example, the species Campanula latifolia is the type of the genus Campanula. The type of family or of a taxon between a family and a genus (for example, a tribe or subfamily) is a particular genus. For example, the type genus of the family Campanulaceae is Campanula, a genus established by C. Linnaeus. Taxa higher than a family do not have types.
