I'm going to weigh in on this one from a little different position. The
company I work for is *ahem* deeply involved in printing and plotting.
We're members of HP's developers program, which aside from the PPA
(Printer Performance Architecture aka winprinter) stuff have bent over
backwards to help us out. That being said, in a conversation with HP I
was told that there is no way they are going to release the specs. If we
were to figure out how it worked then fine, but they weren't telling.
From what I could gather, the protocols aren't proprietary to MS, they
just removed the PCL/RTL interpreter from the printer to make it cheaper.
You still have a rasterization engine, only this time it's in the
winprint.dll instead of on PROMs in the printer.
One of these days I'm going to figure out the rest of it and write a
driver for our rasterization engine. Just haven't had that much time to
kill in a while...
