Can you point me to the thread / message in question?  A search for
".INF" on gmane.org only yielded one thread ("Cups 1.1.20 User Mode
Driver") that isn't very recent.

I don't think that I was being clear enough in my above statement.  I am
looking for a driver that would support multiple heterogeneous *raw*
printers (though using their PCL drivers would be acceptable).

In my case, one printer has native support for PostScript, but the other
requires Ghostscript, which renders too slowly (I think this is because
it's printing at too high of a resolution).

I am looking to get away from using Ghostscript, but now that I think
about it, this brings to mind another question: is it possible to
configure CUPS to print at a different resolution, or is that only
possible through the Windows driver?  I am currently using the Adobe
PostScript printer driver [1], which doesn't appear to have that

Thanks for the pointers.  I have yet to delve into PPD code, so wish me
luck. :-)
