DPI (dots per inch) measures printer resolution in terms of what?

• A. Pixels per Inch on a Display
• B. Dots the Device Can Produce per Linear Inch
• C. Focal Length Range of a Lens
• D. Brightness of a Scene

Answer: (B)

DPI is about how many dots the printer can lay down in one inch along a line. This dot density determines how finely the print can reproduce detail and smooth gradients—the higher the DPI, the more dots there are to form edges and tones, which usually means sharper prints at closer viewing distances. It’s a measurement of physical output, not the pixels on a screen. Think of it as translating a digital image into a pattern of tiny ink or toner spots. The more dots per inch, the finer the potential detail, though real results also depend on halftoning, ink, paper, and viewing distance. This is different from display resolution, which is measured in pixels per inch. The other concepts—focal length range or scene brightness—don’t describe how densely a printer can place dots.
