I have an Olympus D-100 digital camera and an HP 2575 printer. My photo card does not fit into any of the slots. Is there an adapter? Also, when I plug it into the USP slot, nothing happens. How do I do this without downloading to my computer?

What kind of card is it? Yes you should be able to plug youe cam into the usb port and either use it or the lcd on the printer. I would be willing to bet that your card will fit if you can figure it out. Hps help desk is very good and will answere you within minuits of sending a e-mail.
