You can print the contents of WKWebView with viewPrintFormatter. Here is the sample code:

if ([UIPrintInteractionController isPrintingAvailable])
{
    UIPrintInfo *pi = [UIPrintInfo printInfo];
    pi.outputType = UIPrintInfoOutputGeneral;
    pi.jobName = @"Print";
    pi.orientation = UIPrintInfoOrientationPortrait;
    pi.duplex = UIPrintInfoDuplexLongEdge;

    UIPrintInteractionController *pic = [UIPrintInteractionController sharedPrintController];
    pic.printInfo = pi;
    pic.showsPageRange = YES;
    pic.printFormatter = self.webView.viewPrintFormatter;
    [pic presentFromBarButtonItem:barButton animated:YES completionHandler:^(UIPrintInteractionController *printInteractionController, BOOL completed, NSError *error) {
        if(error)
            NSLog(@"handle error here");
        else
            NSLog(@"success");
    }];
}
