Thanks for the code, but I'm not sure if this solves the problem. I went to the Flex2 demo (http://examples.adobe.com/flex2/inproduct/sdk/explorer/explorer.html) and tried the printing demo. If one prints 3 or more pages, one can see that the data grid on the second page could have more rows. (This problem is highlighted when the heading on the first page is large.) In other words, the height of the data grid is not changing according to the space available on the page. With my limited knowledge of Flex2, it seems that the PrintDataGrid should have a method "fitToPage" or something like that which will resize it according to the space left on the page.
