Deskjet 300x C3982A driver needed

Hi,

My computer provides the wrong driver for my Deskjet 300x C39822A.  (It offers a 1440 which doesn't print.)

I tried to install an all-in-one driver but that only works for a 32-bit computer; mine's a 64 bit.

Any thoughts on how I might get a driverfor the C39822A?

Thanks very much!
