Does anyone have ideas about the question 2 ?
2.
when we implement printing with cocoa,
an NSPrintOperation object is created to control the print operation .
NSPrintOperation * printOp = [NSPrintOperation
printOperationWithView:viewToPrint printInfo:printInfo];
[printOp setShowsPrintPanel:YES];
[printOp runOperation];
I got a native printing dialog, So how can I cancel this programtically? Is
it possiable?
