Printer (computing)

In computing, a printer is a peripheral which produces a text and/or graphics of documents stored in electronic form, usually on physical print media such as paper or transparencies. Many printers are primarily used as local peripherals, and are attached by a printer cable or, in most newer printers, a USB cable to a computer which serves as a document source. Some printers, commonly known as network printers, have built-in network interfaces, typically wireless and/or Ethernet based, and can serve as a hard copy device for any user on the network. Individual printers are often designed to support both local and network connected users at the same time. In addition, a few modern printers can directly interface to electronic media such as memory cards, or to image capture devices such as digital cameras, scanners; some printers are combined with a scanners and/or fax machines in a single unit, and can function as photocopiers. Printers that include non-printing features are sometimes called multifunction printers (MFP), multi-function devices (MFD), or all-in-one (AIO) printers. Most MFPs include printing, scanning, and copying among their features.
Consumer and some commercial printers are designed for low-volume, short-turnaround print jobs; requiring virtually no setup time to achieve a hard copy of a given document. However, printers are generally slow devices (30 pages per minute is considered fast; and many inexpensive consumer printers are far slower than that), and the cost per page is actually relatively high. However, this is offset by the on-demand convenience and project management costs being more controllable compared to an out-sourced solution. The printing press remains the machine of choice for high-volume, professional publishing. However, as printers have improved in quality and performance, many jobs which used to be done by professional print shops are now done by users on local printers; see desktop publishing. The world's first computer printer was a 19th century mechanically driven apparatus invented by Charles Babbage for his Difference Engine.[1]
A virtual printer is a piece of computer software whose user interface and API resemble that of a printer driver, but which is not connected with a physical computer printer.

Printer of modem represent sophisticated appliance. Electronic force which there are in a printer [is] equal to electronic force which there are in itself computer. Printer have 6 type that is type of Dot-Matrix, type of Daisy Wheel, type of Ink-Jet / type of Bubble Jet propulsion
From time to time, technology of printer continue to expand so that will do not want to to someone which always relate to other equipments and computer have to continue to keep abreast of. Printer in its Indonesian mean printer ( appliance print). Term ' printer' in this time [is] often used to mention appliance print which incircuit with computer. To connect printer with computer needed [by] a cable which incircuit from printer to CPU computer. In this time, product merk of printer which [is] often used among others [is] Epson, Hewlett Packard ( HP), Canon, Lexmark and still many again. To know clearer about function, type of printer and way of [job/activity] of printer.



Types of Printer "
• Printer Dot-Matrix
Printer Dot-Matrix [is] printer which [is] resolution print him still is very low. Besides when [is] printing, printer this type of its voice tend to to ossify and also the quality of to print unfavourable picture because printed picture will seen like dots which [is] interaction. Generally, type printer of dot-matrix also only having monochrome, that is black colour. But in this time this printer still used many because famous (it) is true ' bandel' ( durabel). Other excess, ribbon of printer dot-matrix much more [is] cheap compared to toner ( tinta) for the printer of type of inkjet and of laserjet " Inkjet Printer
A dot matrix printer or impact matrix printer is a type of computer printer with a print head that runs 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, much like the print mechanism on a typewriter. However, unlike a typewriter or daisy wheel printer, letters are drawn out of a dot matrix, and thus, varied fonts and arbitrary graphics can be produced. Because the printing involves mechanical pressure, these printers can create carbon copies and carbonless copies.
Each dot is produced by a tiny metal rod, also called a "wire" or "pin", which is driven forward by the power of a tiny electromagnet or solenoid, either directly or through small levers (pawls). Facing the ribbon and the paper is a small guide plate (often made of an artificial jewel such as sapphire or ruby[1]) pierced with holes to serve as guides for the pins. The moving portion of the printer is called the print head, and when running the printer as a generic text device generally prints one line of text at a time. Most dot matrix printers have a single vertical line of dot-making equipment on their print heads; others have a few interleaved rows in order to improve dot density.
These machines can be highly durable. When they do wear out, it is generally due to ink invading the guide plate of the print head, causing grit to adhere to it; this grit slowly causes the channels in the guide plate to wear from circles into ovals or slots, providing less and less accurate guidance to the printing wires. Eventually, even with tungsten blocks and titanium pawls, the printing becomes too unclear to read.

• Inkjet Printer
Printer Inkjet [is] appliance print which have used ink to print and quality of to print chromatic picture enough nicely. Speed print the amount of page;yard [at] unegual Inkjet printer, depend on merk type of printer. But [at] printer inkjet, longer printed material run dry him in comparison with laser of printer.
inkjet printer is a type of computer printer that creates a digital image by propelling variable-sized droplets of ink onto paper. Inkjet printers are the most commonly used type of printer. and range from small inexpensive consumer models to very large professional machines, that can cost up to thousands of dollars.
The concept of inkjet printing originated in the 19th century, and the technology was first developed in the early 1950s. Starting in the late 1970s inkjet printers that could reproduce digital images generated by computers were developed, mainly by Epson, Hewlett-Packard and Canon. In the worldwide consumer market, four manufacturers account for the majority of inkjet printer sales: Canon, HP, Epson, and Lexmark, a 1991 spin-off from IBM.[citation needed]
The emerging ink jet material deposition market also uses inkjet technologies, typically piezoelectric crystals, to deposit materials directly on substrates.

• Laser of Printer
Laser of Printer Some of laser of printer its for looking like mechanically photocopy. Energy print him also quite a lot can reach more than 10 sheet per minute. Quality of result print laser of printer even also very good, so that loo like once with its genuiness. Besides printed material quickly run dry. But price of printer this costly enough.
History Early Printer Laser

If you take the air and see a shop, try to pay attention service board which they shown! If seen word " Xerox Copy of Service", hence may simply this place provide document photocopy service complete with its its[his]. Brand Xerox (it) is true stick with something that relate to photocopy.

enunciated it Just, woke up company since year 1906 [in] this America, (it) is true focussed its business [of] area duplication of document. But since Gary Starkweather, one of the researcher [in] Xerox, altering system pengkopi of this document become laser printer, Xerox business start to burst as power of market of printer [in] 70-an.
Consumer of laser printer since [is] first time introduced to continue to expand, begitupun with its technology. this Market noise make one of [the] player of peripheral of laser printer, Minolta, start to think to follow to to produce laser printer. Year 1993, attending product of Minolata Colorscript Laser 1000, what can produce chromatic document and marketed at the price of US$12,499.

Then in the middle of the 1995, Apple Computer start to hang on to coattail Minolta in producing chromatic laser printer by attending Apple Laser of Writer 12 / 600PS capable to print with maximum resolution 600×600 and dpi have internal memory stock [to] equal to 2MB. price of Printer this Apple [is] also sold at the price of cheaper ( US$7,000) compared to printer made in Minolta.

Printer in this time not again simply appliance printer of article of PC ( komputer) to paper. More than that, usage of printer start merambah to is immeasurable [of] lini, just mention as expert print copier or photo capable to duplicate immeasurablely [of] document type.
If problem talking of printer laser which [is] notabene pledged [by] many white colars consumer to produce everyday document. Even some company, document considered to be tip of lance in development of business. Become, there is no need toly [of] surprise if in this time many company which start clever adorn their document [so that/ to be] can win tender or take care of company image.
