Sets whether the receiver is allowed to spawn a separate printing thread.
- macOS 10.0+
trueif the receiver is allowed to spawn a separate thread; otherwise,
NSThread object is detached when the print panel is dismissed (or immediately, if the panel is not to be displayed). The new thread performs the print operation, so that control can return to your application. A thread is detached only if the print operation is run using the
run method. If
false, the operation runs on the current thread, blocking the application until the operation completes.
If you send
can to an
NSPrint object with an argument of
true, then the delegate specified in a subsequent invocation of
run may be messaged in that spawned, non-main thread.
