What to do if the printer isn't printing.

First go to "Management".

Tap "Purge Printer" it doesn't seem to do anything but it clears the Windows print queue. Now try printing again.

If you keep your finger on the button it will turn red and say "No Printout" and definitely won't print. To change this press and hold the button again and it should change back to "Purge Printer" and be green again.
