Ted,

The Word EPS filter has been around for some time. I recall using it years ago. Note that it is listed on that site in both categories of filters for some reason. In the older versions of Word, there was no preview image generated, hence you ended up with a box/frame place holder of sorts, unless you added a preview image before importing.

That being said, one does need to install the import filters from the Office CD, which may not be part of the default settings on all prior versions. It may require going back into the Office set up program to install them.

True, which is the case irrespective of Word/Windows. If you don't have a PS printer locally or accessible via network, you can always install a PS printer driver and print to a file, which can then be printed by a third party if required.

If one has ps2pdf/Ghostscript available, you can also convert the PS file to PDF and then print it via Acrobat or other PDF viewers.

Ted, the critical issue with doing the WMF/EMF conversion on Linux is that the libEMF stuff generates lousy quality (and visually bitmapped) output. I have tried it in the past and gave up, staying with EPS/PDF formats for vector graphics. If one wants to convert the EPS file to WMF/EMF, it is best done on Windows using native Windows drivers, rather than on Linux.

When SVG graphics go mainstream and cross-platform, that should help significantly with this whole issue.
