Answers & Comments
There could be many reasons for this problem..
1. The card is just too big - some readers can only cope with 2 or 4 Gb max.
2. The card's transfer rate may not be compatible - there are many differing speeds at which they can run and not all readers can cope with it.
Have you tried connecting the camer to the printer via USB? pic-bridge etc. will use the camer itself as a card reader avoiding compatability issues.
Hope this helps.
