### Property

# Gtk PrintOperation:allow-async

#### Declaration

    property allow-async: gboolean [ read, write ]

#### Description [src]

Determines whether the print operation may run asynchronously or not.

Some systems don’t support asynchronous printing, but those that do will return `GTK_PRINT_OPERATION_RESULT_IN_PROGRESS` as the status, and emit the `GtkPrintOperation::done` signal when the operation is actually done.

The Windows port does not support asynchronous operation at all (this is unlikely to change). On other platforms, all actions except for `GTK_PRINT_OPERATION_ACTION_EXPORT` support asynchronous operation.

Type:`gboolean`
