How are the printers catogorised based on their working technology?

Printers are typically categorized based on their working technology into three main types: inkjet, laser, and dot matrix. Inkjet printers use liquid ink and are ideal for high-quality color prints, while laser printers use toner and are known for fast, high-volume printing with sharp text. Dot matrix printers operate by striking an ink-soaked ribbon against paper, making them suitable for multi-part forms and carbon copies, though they are less common today. Each type serves different printing needs and preferences.
