While I realize that 16-bit printing typically doesn't improve the final print a lot, it can help under some circumstances (yes, I understand that this point is hotly debated in some quarters). So, it's a bit annoying that HP doesn't plan to introduce a CS3 specific plug-in. The CS2 plug-in supports 16-bit printing in a limited way, at least.
So, (1) Does the printing routine in CS3 allow for 16-bit printing on this printer? If not, (2) can the CS2 plug-in be cajoled into printing 16-bit under CS3? How?
