Seems the first printer was referred to "Dover"?

Subject: Any Interpress fans out there?
I'm in the middle of imaging a set of 5 1/4" diskettes from 1988 containing the
Interpress conformance test suite.
My plan is to
- convert the MS-DOS backup format images to files (trivial)
- find interpress to postscript converter to print the files.
- compare them to the reference pictures to verify I got them all.
The third part is the hard one. I believe there was a document to go along with the
images, so you could verify they printed as expected. I don't think I have that any
more. I'm looking for pointers to an online copy. My search has come up empty.
Of course, the alternative is if someone has an interpress printer. We could just print
them. Perhaps Curious Marc has one alongside the Alto?
