I think that having a computer or printer in your class is a must. Most schools have a printer in their teacher's room but in my last (public) school job they have a lovely printer and it was great. Actually before I left I printed about 100 pages from eslHQ's website, all in colour!
I think that a computer is the new must in the classroom. You can search some new ideas, games for students, exams, learn songs, write and keep student records, play CDs on it and many many more things.
After having the basic essentials in the classroom I would love to have a projector, especially for teaching kids. It's a great help for keeping them on track or for having them to read together..etc.
Don't expect your school to buy those for you those whistleblower
