The term dot matrix printer is used for impact printers that use a matrix of small pins to transfer ink to the page. [17] The advantage of dot matrix over other impact printers is that they can produce graphical images in addition to text; however the text is generally of poorer quality than impact printers that use letterforms (type).
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]
historically, used in human or animal experiments to measure and record data Long extension kymograph: historically, used in or human animal experiments to measure and record data Surface plasmon resonance: Label-free detection of molecule binding. Used to determine kinetic constants of the interaction (k a, k d, K D). Can also be used for ...
Toner is a powder mixture used in laser printers and photocopiers to form the text and images on paper, in general through a toner cartridge. Mostly granulated plastic, early mixtures added only carbon powder and iron oxide ; now there are mixtures that contain polypropylene , fumed silica , and various minerals for triboelectrification .

Organ printing utilizes techniques similar to conventional 3D printing where a computer model is fed into a printer that lays down successive layers of plastics or wax until a 3D object is produced. [1] In the case of organ printing, the material being used by the printer is a biocompatible plastic. [1]
It was used in large-scale printing of paper money issued by the Northern Song dynasty. Movable type spread to Korea during the Goryeo dynasty. Around 1230, Koreans invented a metal type movable printing using bronze. The Jikji, published in 1377, is the earliest known metal printed book. Type-casting was used, adapted from the method of ...
The printers use a 40-micron nozzle that outputs more than 100,000 drops per second of ink. While these printers make microprinting faster and easier to produce digitally, they still have not reached the true sub-pixel size of less than 1 point. [11] The smallest scale microtext a laser printer can produce is 0.5 pt. [12]
Early large-format printers used for printing transfer paper were modified electrostatic plotters using toner, but now are generally large-format inkjet printers using special inks. For small-format printing, inkjet has also become the dominant technology, though special dye-sublimation transfer laser printers are also available.
