Types Of Printers

Explanation
A line printer is an impact printer because it uses a mechanism that physically strikes the paper to create the desired output. In this type of printer, a line of characters is formed by a series of pins or hammers that strike an inked ribbon against the paper, leaving an impression. This impact creates visible characters on the paper. On the other hand, laser printers and inkjet printers are non-impact printers as they use different methods such as electrostatic charges and ink droplets to produce the desired output.

Explanation
A thermal printer is a non-impact printer because it does not use any impact force to create an image on paper. Instead, it uses heat to transfer ink onto the paper, making it a more efficient and quieter printing option compared to dot matrix and daisy wheel printers. Dot matrix printers use a series of pins to strike an ink ribbon against the paper, while daisy wheel printers use a rotating wheel with characters on it to strike the paper. Therefore, the correct answer is Thermal Printer.

Explanation
A laser printer uses a toner cartridge. Unlike ink cartridges used in inkjet printers, toner cartridges contain a fine powder called toner. The toner is transferred onto the paper using an electrostatically charged drum and then fused onto the paper by heat. This process allows laser printers to produce high-quality prints with sharp text and graphics. The use of toner cartridges also ensures that the printer can handle large volumes of printing without needing frequent cartridge replacement.

Explanation
The inkjet printer is the best suited for printing homework because it is affordable, versatile, and can produce high-quality prints. It uses ink cartridges to spray tiny droplets of ink onto the paper, resulting in sharp text and vibrant colors. Additionally, inkjet printers are capable of printing on various types of paper, making them suitable for different types of homework assignments.

Explanation
A printed copy of a document is referred to as a hard copy because it is a physical representation of the document that can be touched and held. Unlike a soft copy, which is an electronic version of the document that is displayed on a screen, a hard copy can be physically stored, shared, and distributed. It provides a tangible and permanent record of the information contained in the document. A temporary copy, on the other hand, implies a temporary or transient version of the document that may not have the same level of permanence or physical presence as a hard copy.

Explanation
Impact printers are known for their noise because they use a mechanical mechanism to strike a ribbon against the paper, creating the desired print. This striking action produces a noticeable sound, which is why impact printers are considered noisy printers.

Explanation
The correct answer is that impact printers make direct physical contact with paper, while non-impact printers do not. This is an important distinction between the two types of printers. Impact printers use a mechanism, such as a print head or pins, to strike an ink ribbon against the paper, creating the desired print. On the other hand, non-impact printers use technologies like laser or inkjet to create images on the paper without any physical contact. This difference in contact affects factors such as speed, print quality, and noise level, making impact printers generally faster but non-impact printers capable of producing better quality prints.

Explanation
Printers are used to print documents, pictures, and receipts. However, they are not used to play videos. Printers do not have the capability to display or play videos as they are designed specifically for printing tasks.
