Let me point out a minor caveat regarding outputting text to 300dpi: you're never going to get text as sharp as with outputting vector art, close, but I tried using 300dpi text as art in a book once, and at small sizes, it still came out fuzzy compared to vector files sent to a PostScript imagesetter.

Say you export some vector shapes, okay text shapes, to Xara EPS file format, and send the file off to the poor misguided publisher that doesn't use Xara for Desktop Publishing but instead has foolishly chosen InDesign. They place that EPS file where it needs to go, and when the PostScript imagesetter hits the vector part of the file, the instructions are to print this area at as high a resolution as the imagesetter is capable.

I haven't seen a lot of difference between a high res bitmap and a vector rendered to dots, but my experience has been is visible, at large display sizes.

My Best,
