Computer printer in Wikipedia page
In computing, a printer is a peripheral device which makes a persistent human-readable representation of graphics or text on paper. The first computer printer designed was a mechanically driven apparatus by Charles Babbage for his difference engine in the 19th century; however, his mechanical printer design was not built until 2000. The first electronic printer was the EP-101, invented by Japanese company Epson and released in 1968. The first commercial printers generally used mechanisms from electric typewriters and Teletype machines. The demand for higher speed led to the development of new systems specifically for computer use. In the 1980s were daisy wheel systems similar to typewriters, line printers that produced similar output but at much higher speed, and dot matrix systems that could mix text and graphics but produced relatively low-quality output. The plotter was used for those requiring high quality line art like blueprints.

Inexpensive printer ink
Cheap printer inks can have the highest quality. This is because printer accessories of this kind are always produced according to generally accepted standards. On the other hand, finding cheaper inks is very cost-effective for individuals and for owners of large photocopying and printing facilities where a large number of different types of printouts are made daily. Good prices for printer inks mean that people who can not afford them can afford rebate actions and introduce various promotions, because they are able to reasonably lower the costs of carrying out orders. In this way, they gain new customers without lowering the quality of services they provide.
Large selection of printer inks
The largest selection of printer inks can be found in computer stores, large sales centers for printer accessories and on the Internet. Of course, a large amount of the goods being served somewhere does not have to prove its highest quality immediately, however, the owners of the best quality stores are trying to have a reliably working printing assortment. This is very important to them, because different types of printer inks are available in many different places and customers dissatisfied with the services provided in one of the stores will certainly find other service providers selling print accessories very quickly. Meanwhile, having a good quality printer inks can become a regular source of income.
