Just wanted to provide some feedback on the Pad Printing function that exists on some Fiery's.

The way it works is completely backwards from the way I'd expect it to work.

To me, I would think you tell it the total number of copies you want in the Copies field, then use Pad Printing to tell it how many copies per pad you want, and it does the math for you like this:
10,000 copies
50 copies per pad
= 200 pads spit out

What I found, is that it works quite obtusely. To actually produce 10,000 sheets in sets of 50, I have to do the math for it (10,000/50 = 200), and enter it this way:
200 copies
50 copies per pad

My $.02
