**Explanation:**
An impact printer is a type of printer that uses a mechanical mechanism to create a physical impact on an ink ribbon or toner, which then transfers the ink or toner onto the paper. This type of printer is typically used for printing documents that require multiple copies or carbon copies.
The options given are:
a) Daisy Wheel: A daisy wheel printer is an example of an impact printer. It uses a circular disk with spokes, each with a character on the end, that spins and strikes the ink ribbon to create the desired character on the paper.
b) Drum: A drum printer is also an example of an impact printer. It has a cylindrical drum with characters engraved on its surface. As the drum rotates, hammers strike the paper against the ink ribbon and the characters on the drum, creating the desired print.
c) Chain: A chain printer is another example of an impact printer. It uses a chain with characters attached to it. The chain rotates, and when a character is in position, a hammer strikes it against the paper and ink ribbon, producing the desired print.
d) Thermal: Thermal printers, on the other hand, are not impact printers. They use heat to transfer the ink onto the paper. The printer heats up the special thermal paper, which reacts to the heat and changes color to create the desired print.
**Conclusion:**
Based on the given options, the correct answer is d) Thermal, as it is not an impact printer. Thermal printers use heat to create the print, whereas impact printers use a mechanical impact on an ink ribbon or toner.
