OK, this is strange Aqua user interface. My printer (a wonderful Kyocera laser printer) is out of toner. Look what happens when I try to print.
A Yellow button? Bizarre. Kind of cool, actually, but it's the first time I've seen something like that (from Apple, at least) since using the earliest Mac OS X betas.
Oh yeah, not enough room for 'Low Toner.' Yuck.
