flow document printout

Question

Greetings, 
I have a problem with printing in WPF.
I am creating a flow document and add some controls to that flow document.
Print Preview works ok and i have no problem with printing from a print preview window.
The problem exists when I print directly to the printer without a print preview. But what is more surprisingly - when I use XPS Document Writer as a printer
everyting is ok, when i use some physical printer, some controls on my flow document are not displayed.
Thanks in advance

Greetings,
I've resolved the problem.I found that binding and sending document to the printer are asynchronously operations. So I made an Appliaction.DoEvents() equivalent in WPF based on Beatriz Stollnitz article. This resolved the problem
