Running print operation on WKWebView I hit EXC_BREAKPOINT and there is all kinds of console spew that looks concerning:

ERROR: The NSPrintOperation view's frame was not initialized properly before knowsPageRange: returned. (WKPrintingView)

** CGContextClipToRect: invalid context 0x0. If you want to see the backtrace, please set CG_CONTEXT_SHOW_BACKTRACE environmental variable.**

WebContent[7743] networkd_settings_read_from_file Sandbox is preventing this process from reading networkd settings file at "/Library/Preferences/com.apple.networkd.plist", please add an exception.

CRASHSTRING: XPC_ERROR_CONNECTION_INVALID from launchservicesd

CRASHSTRING: <rdar://problem/28724618> Process unable to create connection because the sandbox denied the right to lookup com.apple.coreservices.launchservicesd and so this process cannot talk to launchservicesd.

WebContent[7921] The sandbox in this process does not allow access to RunningBoard.

Safe to ignore all this?

Thanks for replying. Sure.

 NSPrintOperation *printOp = [self.webView printOperationWithPrintInfo:[NSPrintInfo sharedPrintInfo]];
if (printOp == nil) 
{
 os_log_fault(OS_LOG_DEFAULT, "Nil print operation."); 
 return; 
}

if (self.view.window != nil)
{
   [printOp runOperationModalForWindow:self.view.window
                                           delegate:self
                                     didRunSelector:@selector(myPrintOperationDidRun:success:contextInfo:)
                                        contextInfo:nil];
}

Hi Macho Man Randy Savage,

Can you please try setting the NSPrintOperation's frame directly like so:

printOp.view.frame = self.webView.bounds

Thank you for your patience,

Yes if I set the frame on printOp.view the EXC_BREAKPOINT issue is avoided.

Otherwise the private WKPrintingView configured for the printOp has a frame of NSZeroRect.
