Secure Digital Printers

Printers are a computer peripheral that lets you produce a permanent copy of text and graphics of documents stored in electronic form, print them on physical media, usually on paper or transparencies, using laser technology or ink cartridges. Many printers are used as peripherals, and are attached to the computer via a cable. Some printers, called network printers have an internal network (typically wireless or Ethernet) interface, and it can serve as a device to print any document to any user on the network. In addition, many modern printers can be connected directly to the electronic media like CompactFlash cards, Secure Digital or Memory Stick, drives USB flash, or image capture devices such as digital cameras and scanners. There are also multifunction devices that consists of the printers, scanner, or fax in a device machine.

Combined with a scanner printers can operate as a photocopier. The printers are designed for low-volume repetitive jobs, which requires almost no preparation time to obtain a copy of a document. However, printers are generally slow devices (10 pages per minute is considered fast), and the cost per page is relatively high. For higher volume jobs there are printers, which are machines that perform the same function as the printers but are designed and optimized for printing jobs, such as printing in major newspapers. Printers are able to print hundreds of pages per minute or more. Printers have increased their quality and performance, which allowed users to perform work on your local printer that used to be in shops specializing in both print cartridges, such as ink and paper are three essential elements to make copies with the printers, and know how to choose the most suitable for the type of printing that are carried out can improve performance of the printers to the limits unsuspected. Cartridges for laser printers, the cartridges duration depends on the amount of toner that contains and when the toner is depleted, the cartridges must be replaced. In the case of the cartridge and the OPC (photoconductive sensitive organ) are in separate compartments, when when just the toner just replaced cartridge, but in the event this OPC inside the cartridge should be changed both increase spending significantly.

The situation is most critical in the case of color laser printers. In ink jet printers cartridges life depends on the duration of ink, although many cartridges can be filled again helping to reduce the expense of buying a new one, but the excessive use of a cartridge can cause play their impressions with lower quality. Ink there are two types of ink for printers: * slow drying ink penetrating: mainly used for monochrome printers. * Fast drying ink: are used in color printers because in these printers, inks of various colors are mixed and should dry quickly to avoid distortion. The goal of every manufacturer of inks for printers is that their inks can print on any medium and develop in different chemical compositions paper new types of ink almost daily now, when you want to make a copy of a printer of high quality is using high-quality glossy paper. This work is quite expensive and in the case of wanting to do a lot of impressions of photographic quality cost would be very high. Therefore, the manufacturers develop new printers that can produce high-quality prints on plain paper. Some manufacturers, including Epson, make your own paper.
