I agree that printing would be nice to have. As would be, e.g.,
continues display in the previewer. Or preview abilities for dvi and ps.
Some people might request that as well (and probably rightly so).
However, none of that is currently available in a state to be put in a
stable release right now (IMHO, at least).

Well, printing should work on Linux by use of the command line tool lpr.
This may be available on all typical installations, but I don't know for
sure. Besides, its quite old (there are other, more modern systems like
CUPS, but again you need to have it installed, you need a proper
interface, ...) and options (like which pages to print, ...) are device
specific. So it works, but hasn't been tested thoroughly. The same
system would be used on Mac, but if it's typically available there at
all I have no idea.
On Windows, the postscript code is sent to the printer directly if that
is supported.
If all these methods fail (regardless of the platform), the pdf will be
printed as a sequence of images, just like they are displayed on the
screen. That's very bad, of course, and has been reported to result in
crappy output.

But again: the patch exists, and if someone wants to toy around with it
and/or build a version of Tw that has that patch (or others) included,
he can do that - it's open source. But the official builds won't have it
included from today's perspective.
