Please can someone help me? I have a mac mini (OS 10.4.11) and a Brother MFC-215C printer. I use an SD card in my camera (not SDHC), and this is picked up by the printer so I can upload photos. I've bought a couple of new SD cards and the printer won't pick them up. When I insert the card into the printer the light on the printer is constant (usually when reading a card it flashes on and off). If I then try to insert one of my old SD cards the printer can't read that one either - then if I reboot it can read the old cards again, but not the new ones. Any ideas please? I'm not techie at all and was careful to buy SD cards as I've already had to give away one camera because it took SDHC cards and the printer wouldn't read those.
