No spares available to repair printer just after 2 years

We bought an HP Officejet Pro 6960 printer about 2-3 years back and now when it needs repair , HP says we do not manufacture spares for it any more. #HP i have Canon printer working since 2006. ARE YOUR PRODUCTS TO LAST JUST 2YRS. DO YOU HAVE A SOLUTION ?WHY SHOULD WE BUY THEM!!!!!
