Line printerA line printer prints one entire line of text before advancing to another line. Most early line printers were impact printers. Line printers are mostly associated with unit record equipment and the early days of digital computing, but the technology is still in use. Print speeds of 600 lines per minute (approximately 10 pages per minute) were achieved in the 1950s, later increasing to as much as 1200 lpm. Line printers print a complete line at a time and have speeds in the range of 150 to 2500 lines per minute.
Inkjet printingInkjet printing is a type of computer printing that recreates a by propelling droplets of ink onto paper and plastic substrates. Inkjet printers were the most commonly used type of printer in 2008, and range from small inexpensive consumer models to expensive professional machines. By 2019, laser printers outsold inkjet printers by nearly a 2:1 ratio, 9.6% vs 5.1% of all computer peripherals.As of 2023, sublimation printers have outsold inkjet printers by nearly a 2:1 ratio, accounting for 9.
Laser printingLaser printing is an electrostatic digital printing process. It produces high-quality text and graphics (and moderate-quality photographs) by repeatedly passing a laser beam back and forth over a negatively charged cylinder called a "drum" to define a differentially charged image. The drum then selectively collects electrically charged powdered ink (toner), and transfers the image to paper, which is then heated to permanently fuse the text, imagery, or both, to the paper.
ImprimanteUne imprimante est un appareil, permettant d'obtenir un document sur papier à partir d'un modèle informatique du document. Par exemple, un texte écrit via un logiciel de traitement de texte sur ordinateur pourra être imprimé pour en obtenir une version papier (c'est un changement du support d'information). Les imprimantes ont été conçues dès l’apparition des premiers ordinateurs, pour permettre la consultation et la conservation sur support papier des résultats produits par les programmes informatiques.
Imprimeriethumb|Johannes Gutenberg, inventeur de la presse mécanique à caractère alphabétique mobile métallique à partir de 1450. L'imprimerie est un ensemble de techniques permettant la reproduction en grande quantité, sur support matériel, d'écrits et d'illustrations, cela afin d'en permettre une distribution de masse. Généralement, on utilise des supports plans et la matière la plus utilisée est le papier ou le textile. Ces techniques forment ce que l'on appelle communément la chaîne graphique.
