I think that I found the problem's cause...
I'm printing to PDF Creator "printer".
If I print to another printer, it works correctly.
Maybe an issue with PDF Creator.
I've used a lot of time reading the help to understand how ReportListener works to accomplish what I want that I don't think about to print to another printer before post.
Sorry for my mistake!
