Just stumbled across an ad of a very small Polaroid mobile printer. That one cost 180 euros (but it had wi-fi and many other extras, i'm quite certain these can be found a lot cheaper). That's actually something, that I'd probably take with me for when I'd leave Europe behind, even though it's sort of "high-tec".... But just imagine the faces of children in Africa, Asia or Latin America; their day, or even week, has already been saved just by the fact, that they have met these strange mzungus or gringos, who have arrived with their wonderful motorbikes (those machines to them will be practically as exotic as a space shuttle!) ... and then you can take a selfie with them, AND give them a print of this meeting to keep as a memory! That'll absolutely shoot their excitement through the roof. You could also print them some photos of your home country, I'm quite certain many would be pleased. One other possible use could be to print from the net some maps of day rides to put visible in your tank bag.. (dunno how up to date navigator maps are these days, maybe you won't actually have this kind of need at all). Or hey, if you happen to lose some important documents along the way, you're already carrying the cure to the problem LOL !! Even if you do not go for something like that - I admit it would be a bit of work (...and you could often be demanded to print dozens of photos to satisfy every child, as you will have huge crowd gatherings around you whenever you stop in certain places!) - it might be a good idea to think of just something very small, that you can carry, and give to the poor children. For example, a friend of mine used to take the small toothbrush/paste sets that hotels often offer guests, and gave those. Something, that represents your home country, would also be nice to give (sorry to bring this up now, as I know you have just left home - but maybe you already thought about something like this!) Have a good time, ride safe, and hoping we can meet in person, once you guys hit Scandinavia!
