Explanation
An impact printer physically strikes an inked ribbon against the paper, which is the only print technology capable of creating an impression through multiple layers of carbon or carbonless paper.
Common mistakes.
- A. An inkjet printer sprays microscopic droplets of liquid ink onto the top sheet only - it applies no physical pressure and cannot transfer an impression through carbon paper layers.
- B. A thermal printer uses heat to activate a chemically treated paper surface - it applies no physical striking force and cannot activate carbon paper.
- C. A laser printer uses a toner-based electrophotographic process with a fuser applying heat and pressure to the top sheet only - it cannot transfer an imprint through multiple carbon layers.
Concept tested. Impact printer use with carbon paper multi-part forms
