Which statement about printing resolution is true?

• A. Higher dpi always reduces file size
• B. 300 dpi is a common printer resolution
• C. 72 dpi is ideal for fine prints
• D. DPI does not affect sharpness

Answer: (B)

Understanding printing resolution means recognizing that dpi (dots per inch) determines how densely a printer places ink to recreate detail. More dots per inch generally means finer detail and sharper edges, but it also means larger file sizes and longer print times.

The statement that 300 dpi is a common printer resolution is the best answer because, in practical printing, 300 dpi serves as a reliable baseline that yields good visual quality while keeping file sizes reasonable. It’s a standard target for many consumer and professional printers, providing crisp text and photos without demanding prohibitively large digital files. Higher resolutions like 600 dpi or more exist for very fine work, but 300 dpi is the typical, widely used standard.

The other ideas don’t fit. Higher dpi doesn’t automatically reduce file size; it usually increases it because more detail data is stored. 72 dpi is a screen-resolution value and doesn’t deliver the detail needed for high-quality prints. DPI does affect sharpness—the more dots per inch, the crisper the print can look.
