Is there anywhere in San Juan I can print off boarding passes?

I don't know in San Juan de los Terreros but if you are able & willing to drive for half an hour you can get them printed off at Forget Me Not at the Las Buganvillas roundabout between Vera and Garrucha.

again thanks for your reply,  Neil
