A printer is a hardware output device that is used for printing documents on paper. It can either print text, graphics or a combination of both. It converts the information present on a computer into hard copies, a requirement of many offices and households today. Moreover, it can also help in creating other documents such as posters and business cards.
It prints a physical copy of digital data present on your computer, and can be connected to it in various ways such as USB, a short-range radio like Bluetooth, a local network using cables (such as Ethernet) or wirelessly through Wi-Fi. Depending on your needs and budget, you can choose from an inkjet printer or laser printer.
The most important part of any printer is its Print Head, which picks the ink and puts it on the paper according to the instructions from the computer device that it receives. The printer can use different types of ink to produce a variety of colors and images on the paper.
The first mechanical printer was invented by Charles Babbage for his Difference Engine in the 1800s. Inkjet printers were introduced in the 1960s by Hewlett-Packard and are one of the most popular forms of today’s printers. Laser printers have largely replaced dot matrix and inkjet printers, mainly due to their higher quality of print and speed. They are also more reliable, require less maintenance and have a lower cost of operation.
