Compile and run the application on an Android device or emulator that is running Android 4.4 or later. When the application has loaded, touch the “Print Document” button to initiate the print job and select a suitable target for the output (the Save to PDF option is a useful option for avoiding wasting paper and printer ink).
Check the printed output which should consist of 4 pages including text and graphics. Figure 86-3, for example, shows the four pages of the document viewed as a PDF file ready to be saved on the device.
Experiment with other print configuration options such as changing the paper size, orientation and pages settings within the print panel. Each setting change should be reflected in the printed output, indicating that the custom print document adapter is functioning correctly.
