Hello, this can do double sided by the usual method of printing odd sides first and then reloading these copies and printing the even sides. It does have an automatic document feeder, however it doesn't have the completely automated 'page turner' to feed both sides of a double sided document to the scanner.
Overall, I'm very pleased with this printer especially as it prints wirelessly from a smartphone or iPad.
Separate ink cartridges are very cost effective and I have not been disappointed with 'generic' replacements.
It is suggested that future software updates might inhibit non genuine Epson cartridges so I don't automatically update the software.
You have to put it on photo paper mode through the menu. Depends how heavy the card is but u might have to stand there and assist. But Don't forget to change it back to normal paper mode after u hv finished with printing on card or it will take an age to print and use up alot of ink.
if you have updated your printer then you can only use Epson ink... if you haven't then you can use the cheep ink Compatible @ any of the buyers on Amazon which they have many of...) run a search on Amazon on your printer and make sure you ask the search for ink :)
