This is a message mainly directed to the Mexican members of board.
I need to know how you say "double sided" or "Simplex / Duplex" when refering to the functions of a copiers. For example: This copier is capable of making 15 double sided copies per minute.
I know the latin term Recto-Verso, widely used in French, is also used in English on some occasions. But Simplex / Duplex is much more popular. I need to know the equivalent in Mexican Spanish por favor.
Muchas gracias para su ayuda.
