Printing Bing Maps

I have ran into this problem serveral times.... when the end user prints the maps some of the tiles are not finished rendering and look blurred.  its obvious the map is not finished rendering.  I have solved this issue in the past by using setTimout but I am wondering if there is a better method of detecting when the maps is finished rendering  I am tried using map.tiledownloadcomplete but it fires prior to the imageChanged event fires or the viewChangeEnd event fires.
is there a way to programacticaly know when the map is finished rendering all its tiles?
