I hope this is the right sub-forum.

My middle school wants to take pictures at dances etc.

Basic posed shots. students get a pic with there friends, and then print out the photo while they wait.

What I have for gear is a Canon EOS XTi, and a 430ez flash.

What I think I need, is another flash or strobe, pocket wizard, good quality fast printer, a cable or such to send pic to printer or laptop?

Not sure on the best way to do this. we did it the other day, take 10 pics, then load the memory card into a little photo printer. just too slow.

Budget for this stuff should be under 3k. maybe a better lense? (using the stock kit lense)

Any suggestions on setup and gear?
