Answer:
sans-serif
Step-by-step explanation:
Fonts can be defined as a graphical representation of texts which includes a collection of characters such as numbers, letters, symbols etc in various size, color, typeface, design or weight.
A general rule for printing is to use sans-serif fonts for headlines and serif fonts for body text. This ultimately implies that, for any printed work such as novels, books, newspapers etc, it is a general rule for a printer to use sans-serif fonts for headlines and serif fonts for body text in order to enhance readability.
Also, it can be reversed in some instances by using a serif font for headlines and a sans-serif font for the body of a text.
