The print industry will print in resolutions up to 2400dpi depending on the intended view distance. If 2400dpi is the ultimate premium for a handheld print then phones still have a lot of catching up to do.
That table is purely relative to the mass-market options and tries desperately to make a case for buying a TV in 2017 which only supports lower resolutions than were common a decade ago. Looking at you, "HD" in 720p.
- haikuginger 10y agoPreviously worked in a photographic print lab; digital wet labs (that use R, G, and B lasers to expose traditional emulsion-based photosensitive paper) operate at 300dpi. Photographers dont target higher than 300dpi for any prints, and for large prints, it's perfectly acceptable to go down to 100dpi.

- nitrogen 10y agoThat's probably a 2400dpi halftone (or similar) resolution. To compare to ppi (pixels per inch), you need to decide how many gray levels you want. Assuming the 2400dpi is a grid, and you want >= 256 shades, you need a grid square of 256 dots (16x16). This is all rather handwavey though, as two-tone b+w prints truly would be 2400dpi. So 2400dpi might be comparable to 150ppi for photographic images.
