+  * debian/patches/30_newprinter-driver-download-override-false-error-alarm.patch:
+    Fix for the infinite loop fix of 1.4.2+20130920-0ubuntu3: Now the loop
+    is terminated when install-printerdriver outputs "done" but perhaps
+    somewhat early (race condition?) as this causes a false alarm of an error
+    exit of install-printerdriver, telling to the caller that the driver was
+    not installed, letting the caller not reload the system's PPD list and so
+    the freshly installed driver does not get found by the subsequent print
+    queue setup. With this we should have a working fix for LP: #1248303).
