I bought Geeetech Prusa i3 Pro B 3D-printer . Motherboard is GT2560. Printing quality is good and accurate. I have been printing with USB connection to my PC.  So i tried to print from SD-card, but printer did not recognize the card. Printer said that "card inserted", but when i go to menu there is only "no SD card" option and it is empty. I have tried different SD-card with various sizes (128 mb, 512 mb, 1028 mb, 4 gb) and also SDHC and SD cards. I have also tried to format cards in FAT, FAT32, NTFS formats. G-codes has been also in root directory of SD-card. Do you have answer or solution to my problem?

Please help

I didn't find the right solution from the internet.
