A printer is a device that accepts information and prints it on paper. It can be used to print text, numbers, or images.
Parts of a Printer
The parts of a printer include a power supply, a printer head, and an ink cartridge. It also includes a paper feed assembly and a stabilizer bar.
Connections and Interfaces
The printer can connect to a computer via a wired or wireless connection, depending on the model. These connections allow the printer to communicate with a computer and send its printing commands.
Ink Cartridges and Toners
A color printer can use ink cartridges that are comprised of black, cyan, magenta and yellow inks. These cartridges can be replaced when a set number of pages are printed.
Resolution: The resolution of a printer (the sharpness of text and images) is usually measured in dots per inch, or dpi. More expensive printers can achieve a higher resolution, typically 550 to 600 dpi.
Printer Drivers
A printer driver is software that translates the instructions sent from your computer’s operating system or application software into a format that the printer can “understand.” The language the printer can understand varies from one type of printer to another, but this translator is essential for almost any type of software to work with a printer.
Some printers also have functions such as scanning, faxing and hole punching. These printers are called multifunction devices and can be useful for businesses that need to make many copies of documents.
