POOR QUALITY PICTURES FROM MEMORY CARD

I RECENTLY PURCHASED A PANASONIC LUMIX DMC-FX3 DIGITAL CAMERA. WHEN I PRINT OUT THE PICTURES FROM THE MEMORY CARD, THE IMAGES ARE ALL SPECKLED WITH BLUE, GREEN, PINK AND YELLOW. THE PICTURES LOOK PERFECT ON THE SCREEN ON MY PRINTER, BUT ENTIRELY DIFFERENT WHEN PRINTED. MY PRINTER IS FAIRLY NEW (HP PHOTOSMART C5180/ALL IN ONE) AND I HAVE NEVER HAD A PROBLEM BEFORE PRINTING FROM A MEMORY CARD WITH MY OTHER CAMERA ON THIS PRINTER. PLEASE INFORM ME WHAT THE PROBLEM MIGHT BE. THANK YOU
