A. Comma

Explanation:

In computer technology, a printer is an electronic output device (peripheral) that is used for the printing of paper documents (texts and images).

Generally, the standard text procedure 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.

Sometimes, when printing a document, an end user may wish to print multiple pages at a goal without any break. In order to achieve this, the user should enter the number of the pages while separating them with a comma in the print dialog box such as 1, 3, 15, 20.

Hence, it is necessary to separate page numbers with a comma when printing multiple pages of a document.

Additionally, you should use a comma for a non-sequential page (1, 3, 7, 15) and a dash for a sequential page (1-9) when printing multiple pages of a document.
