That's like centaur. You need at least a 600dpi printer to make that font work, and higher is better, as the verticals are very thin. However, with the verticals so thin, it is a font that can be quite legible at very small point sizes, like 10, 8, and 6, as long as the paper and printer can support it.

It's really good for home publishing on higher quality gear (at least, for publishing stuff where a classic font is appropriate) because you can take something like A4 and turn it into a quarto of A6 with very small type and still get something you can read.
