Question: is 300 pixels per inch the same as 300 dpi?
Answer: DPI: Dots per inch. It is similar to PPI, but the pixels (virtual drive) are replaced by the number of points (physical drive) in a printed inch. ... 300DPI for example, equals 118.11 PPI. For a good printing 300 DPI is standard, sometimes 150 is acceptable but never lower, you may go higher for some situations.
