My printer messed up when I tried to print off my Infopass appointment letter for Oklahoma City. I've been back on the USCIS website over and over and followed the links it told me to print off a new letter but it just will not bring up my appointment letter again to print off.
I did get a chance to write down the confirmation number etc. The appointment is first thing tomorrow morning so I can't even call USCIS helpline as it's closed. Does anyone know if they will still let me in without the letter if I have all my Identification and stuff?

What about scheduling a second one, and then cancelling the first? It seems like you shouldn't need the letter, but maybe for security.

Good luck!

If you have a confirmation number, you could probably give it to them, and explain your situation about your printer and see if they will still let you inside.

Or, you could do as riblet suggests and cancel your appointment for tomorrow, and reschedule another one.
