maybe scriptedPrint() ?

Wouldn't that make it feel like it does something? it is just setting values in
the controller and does nothing without startPendingPrint() so I felt like
giving it the name of an action was not really appropriate...

+        PrintingController printingController = PrintingControllerImpl.getInstance();
+        if (printingController == null)
+            return;
+
+        printingController.setPendingPrint(new TabPrinter(this),
+                new PrintManagerDelegateImpl(mContext));
+    }
