Yes, that is true. What I am not sure about as I've not done the
testing to support it, is whether just changing the PPD and
re-running cupsaddsmb will result in the client getting the new ppd
installed (our login script maps the printers on this site). If it
does then swapping out a printer should be as simple as changing the
ppd on the server.

One of the things about Postscript is that it tends to degrade
reasonably well. I'm fairly confident that in most cases you could
send a file that (for example) requests duplex printing to a printer
without that feature and it will still print (but without the duplex

You could roll your own !
I don't know if you've looked at the contents of a ppd, but they tend
to be fairly easy to understand (if a bit large for a complex
printer). If you started with a complex printer ppd and stripped out
the bits you don't need then you could end up with something that
would just have the features you want, and I think you would probably
find the output reasonably portable.
