Mac OS 10.13: NSPrintOperation with runOperationModalForWindow

Hello,


I am using NSPrintOperation with runOperationModalForWindow as following :


NSPrintOperation *op;
  NSPrintInfo *myPrintInfo;

myPrintInfo = [[NSPrintInfo alloc] init];
//
//     Set attributes of myPrintInfo
//
op = [NSPrintOperation printOperationWithView: detailsTextView printInfo:myPrintInfo];
  [op runOperationModalForWindow:[self window] delegate:nil didRunSelector:NULL contextInfo: NULL];



With the above code, It is working fine for all OS , except 10.13. On 10.13 OS for remote type Printer, execution hangs at runOperationModalForWindow. Following is sample where it hang:

Here what cares needs to take?

Did you try setting the delegate to [self window] ?

Thanks for reply. tried with delegate [self Window] , It not works.


When TextEdit performs same Print options on that machine , It will also hangs for some 2 to 3 mins with Stack given below. Also regular Print activity seems slower on same machine.
