Qt Printing QTextDocument problem (truncated text)

[giowck]

Hello guys,

I' trying to print a QTextDocument with custom header and footer.
I found this nice code: http://developer.qt.nokia.com/faq/an..._qtextdocument

It works great, except that sometimes the text gets truncated on half page, so that it's not readable... Look here the result: http://dl.dropbox.com/u/1511663/test.pdf between page 2 and 3!

I think this is something related to page size.. But I don't know how it can be fixed, what is the problem?

Hope you can help with some hints. I don't expect you write full code for me, but I hope you can help me with some hints!

My full code is attached as test.zip

Thanks

ps. this is a great forum, thanks!
