For arbitrary clients this is impossible in principle because they may
be drawing individual pixels. Only if they were restricted to drawing
higher-level objects (e.g. lines)  would there be a possibility of finding
out what objects they were drawing and redrawing them for hardcopy at
higher resolution. Of course, individual applications can often generate
hardcopy at better than monitor resolution, because they may have available
the abstract representation of the image. For example, my time-series
editor produces window dumps that look better than screen dumps because
I redraw the image from the internal representation in Postscript or PIC.
