You don't want to do that for anything but creating a small image on a
web page or having a quick look.  By converting the image to bitmap, as
you do by taking a screenshot, you lose all the vector information, thus
preventing you from preserving quality when printing or resizing the
image.  Additionally, bitmap plots are generally much larger, and
compressing them using a lossy format (jpeg) creates visible artifacts
on the border of lines and characters.

In summary, to obtain good quality always use a vector format (ps, pdf
or others).  This is compulsory for professional quality plots.
