I have already been looking at eps files, but it turned out to be much
more difficult than I anticipated. But I plan to give it another try later.

Unfortunately there are problems printing with some printers. Printing
seems to be the most difficult thing to get working. But when it works
Graph will use the native resolution of the printer, which should give
the best result.
When you save as an image and print that, you will probably get the best
result if you use a metafile (emf) instead of a bitmap.

Yes, I hope I will be able to make it work in a later version, and I am
glad to hear that there is an interest for it.

I have it on my todo list, but as you say yourself it is much more
difficult. It will probably take some time before I have it implemented
as there are a lot of easier things I like to implement first.

I rather want help with more local things, like creating eps files or
updating the help file, instead of 3D abilities which requires a major
redesign. Unfortunately I don't know how to find such help.
