Printers & Copiers
In this category we list a selection of different printer. These are all carefully selected by our extensive testing process, reviewed and function properly. Printers are classified by their printer technology and provided with different techniques. The choice of a particular printing technology and a particular brand of printer large impact on the cost of the printer, its operating costs, speed, quality and durability of the documents as well as the noise level of the device. Some printer technologies work with certain types of physical media such as Carbon paper or transparencies. A second aspect of printer technology that is often forgotten is the contained liquid ink, which is brought from an inkjet head or fabric ribbon on the paper and absorbed by the paper fibers, so documents can be printed with liquid ink, for example, in inkjet printers. These documents are more difficult to change than the printed with solid color documents in a printer that does not penetrate below the paper surface. Important documents or photos can thereby be printed , for example, with liquid ink on special paper control, so changes can be detected in time. This is for security of documents.
A brief overview of the different printing techniques used next:
Toner - based laser printer
A laser printer quickly produces high quality text and graphics. As with digital photocopiers and multifunction peripherals (MFPs ), laser printers employ a xerographic printing process and are different from analog copiers. The image is formed by scanning a laser beam directly on the printer's photoreceptor. Another toner-based printer, the LED printer, which uses an array vonLEDs instead of a laser to cause toner adhesion to the printing drum. Inkjet printers, however, work by driving differently sized droplets of liquid ink onto almost any sized page. These are the most commonly used printer by end users.
A dye-sublimation printer (or dye sub printer) is a printer, which uses a particular printing process and heat to transfer the dye in a medium such as a plastic card, paper or canvas. Dye-sub printers are primarily for high-quality color applications, including color photography and are less suitable for text printing through the use upcoming technology.
Solid Ink Printer
Solid ink printers, also known as phase-change printers known, are a type of thermal transfer printer. They use solid sticks of CMYK - color ink as that of candle wax, melted and fed into a powered by a piezo crystal pressure head. The printing head sprays the ink onto a rotating drum which is coated with oil. The paper then passes over the printing drum, from which the image is immediately transferred to the page. Solid ink printers are commonly used as color office printers, and are excellent for transparencies and other non- porous media. Acquisition and operating costs are similar to those of the laser printer. Drawbacks of the technology are the high energy consumption and long warm-up times from cold.
