I know this is a bit off your issue but when it comes to printing it seems leopard/tiger falls short. I bought a HP all-in-one PSC1315, only to find out most of the features aren't supported by Mac (double sided printing), really quite annoying, even called HP to find out if there was anything I could do, turns out nothing. Now even with an upgrade to leopard, still doesnt work, not to mention now only can print about 50% of the time, the rest it just there waiting to print but nothing happens. Oh well, just a quick restart in to Windows and all is good. Real shame though.
