This question was previously asked in
UGC NET 2018 Paper 1 Question Paper (20-Dec-2018) (Shift 1)
The correct answer is

Dots per inch

The output quality of a printer is typically measured by "Dots per Inch" (DPI). Let's explore this concept to understand why this is the correct answer and rule out the other options.

Explanation:

  • Dots per Inch (DPI): This is the standard unit of measurement for the resolution of printed media. It indicates how many individual dots of ink a printer can produce in a linear inch. A higher DPI means more dots are printed, resulting in higher resolution and finer detail in the image or text. This is the correct answer because it directly pertains to the quality of a printed page.
  • Digits per Inch: This term is not applicable to printers but is more relevant to digital displays or numerical representations where digits or numeric information is displayed or processed. Therefore, it is not the right choice for measuring printer output quality.
  • Dots per cm (centimeter) and Dots per mm (millimeter): While these can theoretically describe resolution, they are not standard terms used in the printing industry for measuring printer output quality. The industry-standard remains DPI, making these options incorrect.

Conclusion:

Based on the explanations above, the correct answer to the question about the measurement of printer output quality is Dots per Inch.

This standard measurement allows us to assess the clarity and detail a printer can achieve, which is crucial for both text and image printing.
