The NeXT LaserPrinter NeXT PN N2000 was a 400 DPI PostScript laserprinter sold by NeXT from late 1988 to 1993 for the NeXTstation and NeXTcube workstation s and manufactured by Canon Inc. Canon . It included an adjustable paper tray, enabling it to print several paper sizes including A4 paper A4 , Letter paper size letter size , legal, and envelopes. It was very similar to other printers based on the Canon SX engine, such as the Apple LaserWriter II series and HP LaserJet II III, although those other printers only printed at 300x300 dpi. Some parts such as the toner cartridge and input paper tray are interchangeable with the HP LaserJet LaserJet II III . The printer used a proprietary high speed serial interface, and was essentially an early Graphics Device Interface GDI printers WinPrinter although it was not Windows compatible , as it used the Display PostScript DisplayPostscript renderer in NeXTStep rather than a hardware PostScript renderer. Despite this it usually achieved close to its rated speed of 8 ppm, as the NeXTStation had a much faster CPU 25 or 33MHz 68040 and greater memory capacity up to 128MB in Turbo models than the rendering engines of contemporary printers. Because NeXTStep used DisplayPostscript extensively in its windowing system, the postscript rendering path was optimized Citation needed date July 2009 , and printed documents had a true output WYSIWYG corresponding to the screen.

Image Kodak LED Printer 20R.jpg thumb Kodak LED printer Image LED printhead.JPG thumb Oki LED printhead An LED printer is a type of computer printer. LED technology uses a light emitting diode array as a light source in the printhead. The LED bar pulse flashes across the entire page width and creates the image on the print drum or belt as it moves past. LED s are more efficient and reliable than conventional laser printers, since they have fewer moving parts . Depending on design, LED printers can have faster rates of print than some laser based designs, and are generally cheaper to manufacture. Laser systems rely on elaborate combinations of rotating mirrors and lenses that must remain in alignment throughout their use. The laser scans from one end of a line to another, then starts on the next line. Unlike laserprinter s, an LED printhead has no moving parts.

File 2008TaipeiPack Linx Barcode Printer.jpg thumb 250px A barcode printer A barcode printer or bar code printer is a computer peripheral for printing barcode labels or tags that can be attached to physical objects. Barcode printers are commonly used to label cartons before shipment, or to label retail items with Universal Product Code UPC s or European Article Number EAN s. The most common barcode printers employ one of two different printing technologies. Thermal printer Direct thermal printer s use a printhead to generate heat that causes a chemical reaction in specially designed paper that turns the paper black. Thermal transfer printer s also use heat, but instead of reacting the paper, the heat melts a wax y or resin substance on a ribbon that runs over the label or tag material. The heat transfers ink from the ribbon to the paper. Direct thermal printers are generally less expensive, but they produce labels that can become illegible if exposed to heat, direct sunlight, or chemical vapors. Barcode printers are designed for different markets. Industrial barcode printers are used in large warehouses and manufacturing facilities. They have large paper capacities, operate faster and have a longer service life . For retail and office environments, desktop barcode printers are most common.

They were introduced in the late 1960s. Such devices were sometimes incorrectly referred to as thermal printer s which is in fact a different technology. Spark printing was a simple and inexpensive technology. The print quality was relatively poor, but at a time when conventional printers cost hundreds of pounds, spark printers sub 100 price was a major selling point. The other major downside is that they can only print onto special metallised paper such paper is no longer readily available.

About the profession the Twilight Zone episode Printer s Devil Image Buchdrucker 1568.png thumb Printing press, circa 1568 A printer s devil was an apprentice in a printing establishment who performed a number of tasks, such as mixing tubs of ink and fetching type.

Derivation The origin of printer s devil is not definitively known. Various competing theories of the phrase s origin follow. Printer s devil has been ascribed to the fact that printer s apprentices would inevitably have parts of their skin stained black by the ink used in printing. As black was associated with the black arts, the apprentice came to be called a devil. Another origin is linked to the fanciful belief among printers that a special devil see Titivillus haunted every print shop, performing ....

Printer friendly pages are designed to fit on an 8.5 x11 or A4 paper size A4 sheet see paper size s and include only the content of the page, along with source information. Printer friendly pages are usually accessed through a link on the standard page. Often the link will be indicated by a printer icon. Designing printer friendly pages with CSS Web page designers can use cascading style sheets CSS 2 media types to create one set of styles for display on a computer screen, and another for printing. For example, navigation areas might be set as display none in the print stylesheet to remove them from the printed output, and sans serif fonts replaced by serif fonts for ease of reading.
