There was a book written by some teachers in Polnad on teaching with no resources. Sorry I can't remember the name but I'm sure if you hit some Polish ELT sites they may turn up for you. i used the book and it was good.
My other suggestion would be to get as much stuff downloaded before you go. That way, even if you don't have aprinter you have ideas that can sget your brain juices flowing.
Good luck with your job.
ps what part of the world are you going to?
