The approach I took with this was to make a QTextDocument, insert a  
QTextTable, and then go through and populate the table with the  
contents of the QTableView. You then print the QTextDocument, and it  
takes care of page breaks and the like. It actually turned out to be  
much easier than I was expecting, although it did take some fiddling  
with the column widths and table borders/spacing to get it right for  
me. That could have just been me being picky about exactly what the  
output looked like though :)
