Summary:
I tried print a web page with WKWebView.
But,It always becomes the blank page.

    [wkwebview print:nil];

#2 At Run the following methods:
    NSPrintOperation *printOperation = [NSPrintOperation printOperationWithView:wkwebView printInfo:printInfo];
    [printOperation setPrintPanel:printPanel];
    [printOperation runOperationModalForWindow:[wkwebView window]
                                      delegate:nil
                                didRunSelector:NULL
                                   contextInfo:NULL];

Expected Results:


Actual Results:


Version:
Mac OS X 10.10.2

Notes:
I know the traditional WebView has following method/property for printing.

- (void)webView:(WebView *)sender printFrameView:(WebFrameView *)frameView
@property (nonatomic, readonly, strong) WebFrame *mainFrame;

If corresponding method/property are available on WKWebview, it might help but I can’t find it in WKWebView.

Also, the traditional WebView has the following method.

- (NSArray *)webView:(WebView *)sender contextMenuItemsForElement:(NSDictionary *)element
    defaultMenuItems:(NSArray *)defaultMenuItems

In a similar fashion, can I add "print" menu item on the context menu of WKWebView?
