Which of the following is a line printer?

Correct option is A

A chain printer is a type of line printer, which means it prints an entire line of text at a time. It uses a continuously moving chain of characters, and the desired character is printed when it aligns with the correct print position. Chain printers are high-speed and were widely used in earlier computing environments for large-scale printing tasks.

Important Key Points:

1. Line Printer: A printer that prints one line at a time, making it suitable for high-volume printing.
2. Chain Printer: Uses a chain of characters to print and is a prime example of a line printer.
3. Speed: Chain printers are faster than dot-matrix or inkjet printers but lack graphical printing capabilities.

Knowledge Booster:

• Dot-matrix printer: Prints character by character, not line by line, using a set of pins to create characters.
• Inkjet printer: Sprays tiny droplets of ink to create text or images, printing character by character or pixel by pixel.
• Laser Printer: Uses laser technology to produce high-quality text and images but prints page by page, not line by line.
• Line printers like chain printers were used in earlier systems where high-speed text printing was critical, often in industrial or mainframe environments.
