Answer 1

The correct answer is Dots per Inch.

Key Points

Dots per Inch (DPI) is a measure of spatial printing or video dot density, particularly the number of individual dots that can be placed within the span of one inch.
Higher DPI means higher resolution and more detail in the printed or displayed image.
DPI is commonly used to describe the resolution of printers, scanners, and computer displays.
For example, a printer with 600 DPI can print 600 distinct dots in a line within one inch, providing high-quality prints.

LPI (Lines Per Inch): Refers to the number of lines per inch in a halftone screen used in printing.
Printer Resolution: Describes the quality of the printed output, often indicated in DPI; higher resolutions yield finer detail.
Image Resolution: The detail an image holds, commonly described in PPI for digital images, impacting the quality when printed.
