I've only had trouble printing to un-supported esoteric printers to the OSX system.
Some times I eventually got a result after some studying and others were just plain Windoze only.
Speed has been the same for both systems for me.
I tend to notice less "bloat functions" on OSX ... at least it preints
Not having drivers for every single printer can be understandable.
I do think that Apple should put more effort to get more drivers to be compatible with OSX. Which is why I lame blame also on Apple and not just the printer manufacture.
However, many times I have just plugged my printer up via USB and then selected it from the print control panel.
overall experience : -1 for apple and the manufactuers.
