Connecter au gestionnaire d'impression

Bonjour
Voici comment connecter au gestionnaire d'impression sous Android:
private void doPrint() {
// Get a PrintManager instance
PrintManager printManager = (PrintManager) getActivity()
.getSystemService(Context.PRINT_SERVICE);

// Set job name, which will be displayed in the print queue
String jobName = getActivity().getString(R.string.app_name) + " Document";

// Start a print job, passing in a PrintDocumentAdapter implementation
// to handle the generation of a print document
printManager.print(jobName, new MyPrintDocumentAdapter(getActivity()),
null); //
}
