Below is the feedback from app producer:
Apple's latest release of iOS 5 has changed the way apps are able to interact with the device. This now means that the one of the printing features in this app for printing from other apps via the AirPrint method is no longer available. Apple's changes for iOS have removed this functionality for all apps - not just ours. All other printing options from other apps via this app are still available and you can still continue to use your existing printer(s).
iOS Apps are restricted by features of the OS and the device so there is no option to bypass the iOS restrictions. We are working with Apple resources to see if there is a way to restore this particular feature in future releases.
We invest a huge amount of our resources in the ongoing development of our apps to ensure our apps provide the most possible printing features for Apple devices. While we are obviously very disappointed that Apple have removed this feature of iOS, our apps were still the best printing apps on the App Store before this feature as we have so many other printing features.
Our staff have been working overtime to evaluate this iOS change. While it is devastating for them to lose one of the app features that everyone put so much time and effort into, we all remain committed to providing the best permissible improvements to our apps for our customers, as we have done in the past.
All of the other printing options are still available such as "Open in", server printing, internal email, iWorks via iwork.com, internal browser, Safari via "zhttp:" etc.
