Thanks for the quick reply. You can see my posts on flexReport and PrintTextArea to see what I'm trying to do. Printing is killing me. People (specially in organizations) do like to print stuff, and more they do like to see what they are about to print before they waste paper. And I really don't like to waste countless hours every single time I want to print more than a few lines of text. Now I'm trying to develop a reusable solution to prevew and print reports and the only (major) feature missing is printing multiple pages of text. Would you bother to take a look at PrintTextArea (http://www.kemelyon.com/printtextarea/) and see if you can give me some help? In the meanwhile I'll try to make good use of your tips :) Regards, Frederico Garcia
