ప్రశ్న 1
Which characteristic fundamentally distinguishes an impact printer from a non-impact printer?
Select an option first. || ముందుగా ఒక సమాధానాన్ని ఎంచుకోండి.
Explanation:
• Impact printers produce characters or images through physical contact between the printing mechanism, ribbon and paper.
• Dot-matrix printers are a common example of impact printers.
• Inkjet and laser printers are classified as non-impact printers because they do not form output by striking an inked ribbon against the paper.
