Subject: HELP NEEDED!!

I made a stupid mistake and wondered if anyone could throw some light on this for me please....i wanted to renew my plus account and made the mistake of entering my details on the bank transfer page instead of the card(paypal page),i only realised my mistake after the information was entered. im using the computer in my works design centre so i have no information about the bank transfer and it said it sent the information to a default printer.looking at the bank transfer page this is normal but i dont know if i have to do anything else to activate it or if i leave it will it just be ignored and not charge me? im terrible with computers and i hate the idea of my information floating about. does anyone know what will happen now that ive sent that bank transfer information? when it comes to things like this im stupid. now i dont want to renew my plus through paypal until i know the situation with the bank transfer.can someone please help me.

You need to find out where the default printer for that computer lives and go and get the print-out - no other way round it I think.
