dev.print() can do this:

The slightly sticky bit is setting up options so that you get
satisfactory text size and aspect ratio on the output. The defaults
are not too bad for exploratory purposes, but getting something to
included in LaTeX was tricky.

[It seems like it is necessary to tweak both the X11 parameters and
the postscript ones if you want to diddle with things like the
pointsize. If so, then there's a buglet somewhere, but I can't really
nail it down.]

And yes, we probably do want a print function/button at some point.
