Imagine a simple PDF file with a bit of text in it. If the text is real text, ie. vector graphics, it comes out looking very good. If I rasterize the same text (or any vector graphics) at the same resolution as the printer then it still doesn't look as crisp as the vector graphics. I would have thought rasterizing a vector to the same resolution as a printer would give vector quality. Is this not this case and is there something that I'm missing?
