Welcome to the curse of SD. From
http://www.sandisk.com/Products/Item...I_SD_2GB.aspx:
"Not all devices support SD 2.0GB cards. Please contact your device
manufacturer for details. "

Does any one know if there is anything I can do so that it will?

Rewrite the firmware in your printer or ask Epson if they have a firmware
update?
