I had a spread sheet that I would put the numbers from ApFill into and it would tell me the cost to print the page.
On one worksheet I had a list of the different consumables and the price we paid for them and there yield. And on the other sheet I had the calculations that would use the numbers from ApFill and the numbers from the sheet with the consumables.
It worked really well. I can't find the file anymore otherwise I would post it.
