Line printer
Chain printer
Laser printer E. None of the above
Answer is Wrong!
Answer is Right!
The correct answer is E. None of the above.
A drum printer, line printer, and chain printer are all impact printers. An impact printer is a type of printer that uses a physical impact to transfer ink to paper. This is in contrast to non-impact printers, which use other methods to transfer ink to paper, such as heat or electrostatics.
A laser printer is a type of non-impact printer that uses a laser to create an image on a drum. The image is then transferred to paper using a toner cartridge.
Here is a brief explanation of each option:
- Drum printer: A drum printer is a type of impact printer that uses a rotating drum to print text or images. The drum is coated with a thin layer of ink, and a print head moves across the drum, applying electrical charges to the ink. The paper is then pressed against the drum, and the ink is transferred to the paper.
- Line printer: A line printer is a type of impact printer that prints one line of text at a time. The printer has a print head that moves across the paper, striking a series of hammers that strike an inked ribbon, which then prints the text on the paper.
- Chain printer: A chain printer is a type of impact printer that uses a chain of characters to print text. The chain is made up of individual characters that are linked together. The chain is wrapped around a drum, and a print head moves across the drum, striking the characters on the chain, which then print the text on the paper.
