There's one more thing. WebView loads requests asynchronously, so you need to block while it is loading the request and laying out the page while taking some time out to run the run loop. So do something like this:
while ([myWebView isLoading])
{
NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
[myWebView setNeedsDisplay:NO];
[NSApp nextEventMatchingMask:NSAnyEventMask untilDate:[NSDate dateWithTimeIntervalSinceNow:1.0] inMode:NSDefaultRunLoopMode dequeue:YES];
[pool drain];
}
[webView setNeedsDisplay:YES];
When this loop is done, any print operation you perform on the web view ought to work.
