Yes, that is good and it is also now mentioned in the manual:
(info "(emacs) Windows Printing")
The problem is that it requires an external program that not everyone has.
I understand that some people choose not to install Ghostscript, but are
there cases where they *couldn't* install it?
I think we should more actively encourage the use of Ghostscript
under Windows. E.g. we may want to provide a link to an appropriate
web-page. And advertize the fact that it would allow them to print to
PDF as well from any application as well (anything that can undermine
Adobe is good in my book).
