SD driver not working

MY SD driver is not working. I have unistalled it and restarted my computer
and it reinstalls it. There is no error on it when I go to Device manager.
When I check to see if it is up dated it says that it already is. The USB
port works that is all part of the driver.
I can not get the my computer to down load the pictures from my printer if I
put the SD card in my printer. The printer does down load the photos but it
will not transfer them to the printer. (The computer will accept scans and
works in everything else.)
