  2. Dot matrix printing - Wikipedia

    en.wikipedia.org/wiki/Dot_matrix_printing

    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 and forth or in an up-and-down motion on the page and prints by impact, striking an ink-soaked cloth ribbon against the paper. They were also known as serial dot matrix printers. [4]

  3. List of printing protocols - Wikipedia

    en.wikipedia.org/wiki/List_of_printing_protocols

    A printing protocol is a protocol for communication between client devices (computers, mobile phones, tablets, etc.) and printers (or print servers).It allows clients to submit one or more print jobs to the printer or print server, and perform tasks such as querying the status of a printer, obtaining the status of print jobs, or cancelling individual print jobs.

  4. Printer tracking dots - Wikipedia

    en.wikipedia.org/wiki/Printer_tracking_dots

    Printer tracking dots, also known as printer steganography, DocuColor tracking dots, yellow dots, secret dots, or a machine identification code (MIC), is a digital watermark which many color laser printers and photocopiers produce on every printed page that identifies the specific device that was used to print the document.

  5. Printer (computing) - Wikipedia

    en.wikipedia.org/wiki/Printer_(computing)

    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] Different types of printers include 3D printers, inkjet printers, laser printers, and thermal printers. [3]

  6. Filter press - Wikipedia

    en.wikipedia.org/wiki/Filter_press

    Practically, maximum filtration rate is obtained when the filtration time is greater than the time taken to discharge the cake and reassemble the press to allow for cloth's resistance. [16] Properties of the filter cake affect the filtration rate, and it is desirable for the particle's size to be as large as possible to prevent pore blockage by ...

  7. Laser printing - Wikipedia

    en.wikipedia.org/wiki/Laser_printing

    Laser 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. [1]

  8. Inkjet printing - Wikipedia

    en.wikipedia.org/wiki/Inkjet_printing

    Inkjet printing is a type of computer printing that recreates a digital image by propelling droplets of ink onto paper and plastic substrates. [1] Inkjet printers were the most commonly used type of printer in 2008, [2] and range from small inexpensive consumer models to expensive professional machines.

  9. Capillary flow porometry - Wikipedia

    en.wikipedia.org/wiki/Capillary_flow_porometry

    This is the traditional approach, in which the pressure increases continuously at a constant rate (figure 1), which can be modified depending the instrument and the user's requirements, and the gas flow through the sample is measured. Again, the number of data points acquired can be adjusted by the user.
