Printers have evolved significantly from early mechanical printers to modern digital printers. Early printers included mechanical printers invented by Charles Babbage in the 1800s and the first xerographic process invented by Chester Carlson in the 1930s. Printers are generally categorized as either impact printers, which use a mechanical mechanism to strike pins against paper, or non-impact printers, which use technologies like laser, inkjet, or thermal to print high quality text without noise. Common impact printers include dot matrix and daisy wheel printers while popular non-impact printers are laser and inkjet printers. 3D printers also represent an emerging technology that can print solid 3D objects from digital models.

4. IMPACT PRINTERS
ADVANTAGES
• They are cheap for large scale printing
• They are useful in sectors where quantity
matters over quality
DISADVANTAGES
• They are slow
• They create noise when the pin strikes
against the paper
• They have low quality
• They use an electro-mechanical mechanism
• A component is struck against paper to print text
• They are mostly used in offices, small organizations
and factories
• Examples are dot matrix, daisy wheel and line printers

6. NON-IMPACT PRINTERS
ADVANTAGES
• They are faster
• Produce very high-quality result
• They make no noise
DISADVANTAGES
• Their ink-cartridges are very costly
• They use latest technologies; Laser, Thermal and Ink-
jet
• They are speedier than impact printers
• Their speed is measured in PPM (Pages Per Minute)
• Examples are laser, ink-jet and thermal printers
