Had no problem at Lilongwe last year on ET getting a printed boarding pass, but was still an odd experience. Mine printed fine, LLW-ADD and ADD-NRT but my partner's did not print out right although we were in the same PNR, her's printed out LLW-BLZ, BLZ-ADD, and ADD-NRT. The agent kept insisting that it was ok and just stay on the plane in Blantyre, but I refused to accept it for fear that if she didn't pass through the gate in Blantyre then she'd be offloaded from the ADD and NRT flights. Finally someone got it straightened out after 10 mins or so for a proper boarding pass LLW-ADD.
