Computer Printers

Printers are machines that attach to computers as peripheral and help in producing a hard copy of any data that is stored in the computer.  On being given a command any document will get printed by a printer attached to that computer.  The printer uses a special ink, filled in cartridges and prints the data on different sizes on desired size of paper.

While many printers are individually connected to a specific computer, many others are connected to a network and are shared by a number of computer users simultaneously.  Such arrangements are very common in workplaces.  Many modern day computer printers also include non-printing features like fax and scan.  They are called multifunction or all-in-one depending on the feature availability in them.

The evolution of printers has seen various types of printers and printing technologies.  These became famous peripherals of the computers with the advent of dot matrix printers.  In such printers the machine relies on pixels or dots to print the document.  These were used quite excessively until the next generation of printers came.

The modern age laser printers can print at a much faster pace and can give output in hundreds.  These are generally toner based printers and are available in both colour and monochrome varieties.  Though some recent research has indicated that laser printers emit some harmful ultra fine particles, yet they still remain the most widely used and most popular printers in the corporate sectors.
