NJ fingerprinting

I am currently working on getting licensed in New Jersey. My last step is getting fingerprinted (and taking the NJ MPJE). I was wondering if anyone knew the timeframe for the paper cards vs the electronic version. I'm taking my MPJE in two weeks (7/24/17) and would like everything to be sorted out by then but the soonest electronic appointment time I can get is next Tuesday (7/18/17, a week before my exam) do you think that's enough time or should I do the paper cards now?

THANKS!
