What are printers?
A printer is a machine that allows text and graphics output from a computer and conveys information onto paper, usually a standard 8.5 x 11-inch piece of paper. Printers vary in size, speed, complexity, and cost. Typically, more costly printers get used for everyday printing or high-resolution colour printing.
Printers for personal computers get divided into percussion and non-percussion. Early shock printers functioned as an automatic typewriter, with a key marking an ink print on the paper for each character printed. At the same time, it is a popular low-cost option.
The most famous non-impact printers are inkjet and laser printers. Inkjet printers spray ink from a cartridge pretty close to the paper as it travels, while laser printers use a laser beam shone from a mirror to attract ink (called toner) to selected areas of the paper while the paper rolls on the drum.
Features to consider before buying a printer
Most current printers allow colour printing. However, they can also get configured for black and white printing. Colour printers are more costly to run because they use two monochrome and one black cartridge or toner, which gets replaced after a certain period. Black, Cyan, Magenta, and Yellow ink cartridges or cartridges. The ink could be mixed or monochrome solid ink cartridges separately, depending on the variety of printers.
The sharpness of text and pictures on paper usually gets covered in dots per inch (dpi). Most low-cost printers give 600 dpi, adequate for most tasks.
If users print a lot, print speed is an essential consideration. Inexpensive printers print only 3-6 sheets every minute. However, faster print rates are possible with a more complex and expensive printer.
Most printers have a small amount of memory, typically 216 megabytes, which the user can expand. More memory than the minimum is beneficial and faster when composing pages with large pictures.
Types of printers
- Inkjet printers
It creates a digital image by spraying ink onto paper. It is the most popular type of personal printer.
- Laser printer
They are used to produce high-quality prints by emitting a laser beam at high speed through a negatively charged drum to detect an image. Colour laser printers get most commonly used in trained settings.
- 3D printers
It is a relatively new printing technology. 3D printing builds a physical article from a digital file. It works by combining layers of material until the print gets finished and the object is ready.
- Thermal printers
They create an image on paper by applying a thermochromic coated paper to an electrically heated print head and creating a picture in the area where the heated film turns black. Sublimation printing is a kind of thermal printing technology that employs heat to carry dye into a material.
- Photo printers
They are similar to inkjet printers but especially gets designed to print high-quality photographs, which needs a lot of ink and speciality paper to keep the ink from smearing.
Having a printer at home is a one-time investment. Students require printers for printing their school/college assignments. There it is more convenient than printing at the stationary. You can also get it at wireandcutter.com
