Picking up BPs for a day trip

[pilot]

Once again, I find myself turning to the near-infinite knowledge that the collective conciousness of this board possesses.

So here's the situation. Early next week I'll be off to AMS for the day from MAN by way of LGW. I'll be OLCI-ing, but since I won't have access to a printer, I'll have to collect the BPs at MAN.
Will I be able to pick up my AMS-LGW-MAN BPs at MAN the same time as I pick up my MAN-LGW-AMS ones?
If not, will I be able to get the BPs at a SSCI machine in AMS without the card used to purchase the ticket? (i.e. with only my PNR)
