Explanation:

Introduction:
In this question, we are given a scenario where the person is used to sending and receiving messages by printing. We have to identify what device or medium allows this type of communication.

Options:
Let's analyze each option and see which one fits the given scenario.

1. Television:
Television is an electronic device that allows us to receive audio and visual information. However, it does not involve printing messages. Therefore, option 'a' is incorrect.

2. Radio:
Radio is a device that allows us to listen to audio broadcasts. It does not involve printing messages. Hence, option 'b' is incorrect.

3. Fax:
Fax, short for facsimile, is a device that allows us to send and receive printed messages or documents over a telephone line. It uses a technology called telephonic transmission. The sender places the document on a fax machine, which scans and converts it into electronic signals. These signals are then transmitted to a receiving fax machine, which prints out the document. Therefore, option 'c' is correct.

4. Newspaper:
A newspaper is a printed publication that contains news articles, advertisements, and other information. While it involves printing messages, it does not allow for direct sending and receiving of messages by individuals. Hence, option 'd' is incorrect.

Conclusion:
Based on the analysis, the correct answer is option 'c', which represents the Fax machine.
