print_file
Description:
public async bool print_file (Window? parent, PrintSetup? setup, File file, Cancellable? cancellable) throws Error
This function prints a file.
If you pass `NULL` as setup, then this method will present a print dialog. Otherwise, it will attempt to print directly, without
user interaction.
The callback will be called when the printing is done. It should call [method@Gtk.PrintDialog.print_file_finish] to obtain the
results.

| parent |
the parent `GtkWindow` |
| setup |
the `GtkPrintSetup` to use |
| file |
the `GFile` to print |
| cancellable |
a `GCancellable` to cancel the operation |
| callback |
a callback to call when the operation is complete |
| user_data |
data to pass to |
