Maybe it could have multiple backends.  I want to keep the flexibility of
being able to pipe output to other filters for creating PDF files, etc.

I looked at CUPS.  There is sourcecode (and links for RPMS) at
www.cups.org.  Looking at the source it's not immediately obvious to me if
you can get status about paper, but I didn't look at it too carefully.  I
know this might be a Linuxism, but doesn't the newer parallel port code
support sharing between multiple processes?
