Drum printers belong to which of the following categories?

Correct option is D

Drum printers are classified as line printers because they print an entire line of text at once, unlike character printers that print one character at a time. They use a rotating drum with raised characters that strike against an ink ribbon to produce output on paper.

Important Key Points:

1. Drum printers are impact printers—they physically hit the paper through an ink ribbon.
2. They are known for high-speed printing, especially in industrial or large-scale batch printing environments.
3. They are mostly used for printing large volumes of text with limited formatting needs.

Knowledge Booster:

• Thermal printers use heat to transfer ink or create images on thermal paper and are used in POS machines and receipts.
• Inkjet printers spray tiny droplets of ink onto the paper and are used for high-quality prints but are much slower.
• Laser printers use laser beams and toner to produce high-resolution text and graphics, but they do not strike the paper.
