Summary [Qt] [Regression] printing to a printer produces only blank pages
Timo Schlüßler

When printing to a printer via QWebFrame::print(QPrinter *) the printer just prints blank white pages. When printing to a file (ps or pdf), everything gets printed fine. Testcase: int main(int argc, char *argv) { QApplication app(argc, argv); QWebPage page; QWebFrame *frame = page.mainFrame(); frame->setHtml("<html><body><p>test</p></body></html>"); QPrinter printer; frame->print(&printer); } Printing anything else works very well, so that's the reason for me posting the bug here but not on qt's bugtracker. The bug is known to exist in Qt 4.7.2/3 but in 4.7.0 it worked.

I just tried with QtWebKit 2.2 on Mac and printing works fine here. I don't have a windows box to test. Could you please: -test spinning the even loop. I doubt we really support ending the application without any further event handler. -Try with QtWebKit 2.2 Raising as P1 (regression) until someone test 2.2 on windows.

Adding "return app.exec();" doesn't change the print-output in any way. Using a freshly compiled QtWebKit (I used tag qtwebkit-2.2-week20 from gitorious.org/webkit/qtwebkit) doesn't change anything as well.

May be a bug in Qt then? Because between Qt 4.7.0 and Qt 4.7.3 I doubt WebKit in Qt changed at all.

Okay, I will report it as a bug to Qt then.
