Your memory card is SDHC. Many card readers and a lot of SD supporting devices are NOT compatible with SDHC memory - they will need a firmware update which adds SDHC support but it's quite likely this isn't available for your printer or memory card reader, so you are stuck with SD (ie. up to 4GB) only memory support.

There's not much you can do for your printer unless HP make available new firmware, nor is it likely your card reader can be upgraded. Your best bet would be to buy a SDHC card reader - SanDisk include such a card reader with some of their memory cards (I got one with my SanDisk 4GB SDHC memory card - it's called a "MicroMate" and plugs into a USB2 port). Or buy a multi-card reader that is SDHC compatible.

Assuming your memory card is genuine (if you bought the memory card from eBay there's a good chance it might be fake!) it will work once you have an SDHC comptaible card reader.
