    en.wikipedia.org/wiki/Teletype_Model_28

    The keyboard extends 4.5 inches. This machine, using the standard synchronous motor, uses less than 1.5 amps at 115VAC 60 Hz. The recommended operating environment is a temperature of 40 to 110 Fahrenheit, a relative humidity of 2 to 95 percent and an altitude of 0 to 10,000 feet. The printing paper is an 8.44 inch by 4.5 inch diameter roll.

  3. Dot matrix printing - Wikipedia

    en.wikipedia.org/wiki/Dot_matrix_printing

    Dot matrix printing, [1] sometimes called impact matrix printing, is a computer printing process in which ink is applied to a surface using a relatively low-resolution dot matrix for layout. Dot matrix printers are a type of impact printer that prints using a fixed number of pins or wires [2][3] and typically use a print head that moves back ...

    The Giga Press program is a series of aluminium die casting machines manufactured for Tesla, initially by Idra Group in Italy. Idra presses were the largest high-pressure die casting machines in production as of 2020, with a clamping force of 55,000 to 61,000 kilonewtons (5,600 to 6,200 tf).

  5. Letterpress printing - Wikipedia

    en.wikipedia.org/wiki/Letterpress_printing

    Letterpress printing is a technique of relief printing for producing many copies by repeated direct impression of an inked, raised surface against individual sheets of paper or a continuous roll of paper. [1] A worker composes and locks movable type into the "bed" or "chase" of a press, inks it, and presses paper against it to transfer the ink ...

  7. Near letter-quality printing - Wikipedia

    en.wikipedia.org/wiki/Near_letter-quality_printing

    Near letter-quality (NLQ) printing is a process where dot matrix printers produce high-quality text by using multiple passes to produce higher dot density. [1] The tradeoff for the improved print quality is reduced printing speed. Software can also be used to produce this effect. [2][3] The term was coined in the 1980s to distinguish NLQ ...

  8. Drafting machine - Wikipedia

    en.wikipedia.org/wiki/Drafting_machine

    A drafting machine is a tool used in technical drawing, consisting of a pair of scales mounted to form a right angle on an articulated protractor head that allows an angular rotation. [1][2] The protractor head (two scales and protractor mechanism) is able to move freely across the surface of the drawing board, sliding on two guides directly or ...

    They were also called "132-column printers". In computing, a printer is a peripheral machine which makes a durable representation of graphics or text, usually on paper. [1] While most output is human-readable, bar code printers are an example of an expanded use for printers. [2]
