You missed to tell us something about your versions.

Works here with:
python: 2.6.2
sip: 4.12.4
qt4: 4.7.1
pyqt4: 4.8.5
os: Linux

Note, that printing is implemented quite differently in Windows and 
Linux, and QWebView is somewhat complex in itself.. It might be a 
printer _driver_ problem, which aren't that uncommon with Windows (but 
who cares: it's the industrial standard by definition).
