Sony PSP Memory Card
ok so I have a Sony PSP with a SanDisk Memory Stick PRO Duo 1GB and a HP Photosmart 2710 All-in-One with Memory card support (CompactFlash Type I and II, Memory Stick, Secure Digital/MultiMediaCard/Secure MultiMediaCard, SmartMedia, xD-Picture Card). I've tried connecting it in the SD slot, but that didn;t work. The I tried another one with the Memory Stick logo on it (kind looks like an M with three lines underneath.. like on the Memory Stick), but its too short to fit.
Do I need some kind of adapter or whats going on?
Your going to need the adapter from this list.

PSP uses a MEMSTICK DUO. Your printer has a MEMSTICK slot. Two different things. As Train said, you need an adapter. The Sandisk should have come with it.
