Giampaolo, The javax.print has an API dependency<http://download.oracle.com/javase/6/docs/api/javax/print/ServiceUI.html> on Java AWT, which is a desktop windowing UI. This will make it quite difficult to implement the full API on Android. If you only need a narrower API, the job may be significantly easier.
That said, Dalvik provides documentation<http://code.google.com/p/dalvik/wiki/JavaxPackages>for supplementing the standard APIs. Cheers, Jesse
