NSPrintOperation *printOperation= [NSPrintOperation 

printOperationWithView:view1];
[printOperation runOperation];

Answer 1

You can suppress the display of the NSPrintPanel object by sending setShowsPrintPanel: with a NO argument to the NSPrintOperation object before running the operation.

Just like this:

NSPrintOperation *printOperation= [NSPrintOperation printOperationWithView:view1];

[printOperation setShowsPrintPanel:NO];
[printOperation runOperation];
