1080p 13": 169 dpi
4K 13": 338 dpi
Laser printer: 600 dpi
Photo printer: 1200 dpi
Laser printers use 600 dpi because most readers who appreciate typographic design and sharp fonts do not consider 169 dpi to be "perfectly sharp" even with all subpixel cleartype tricks enabled. Knuth's Computer Modern font that TeX/LaTeX use by default looks terrible below about 300dpi because its sharp serifs cannot be rendered correctly. I can't stand my 227 dpi MacBook Air M1 because the fonts on my Surface Pro (267 dpi) are so much sharper, especially because Big Sur eliminated subpixel cleartype tricks so fonts are now worse on Mac screens than they were when the 2012 Retina MBP came out. But a 338 dpi 4K display on a Dell XPS 13 is a noticeable improvement over the 267 dpi Surface Pro. |
