Hello Brian,

thanks a lot for pointing me to that thread. Indeed, the described 
problem looked exactly like mine.
So, I did a full wheezy upgrade and then performed :
"lpadmin -p Stylus_Photo_750 -o usb-unidir-default=true"
and the problem was gone. Then I ran :
"lpadmin -p Stylus_Photo_750 -o usb-unidir-default=false"
and it was back, then :
"lpadmin -p Stylus_Photo_750 -o usb-unidir-default=true"
and it was gone again.
So, it Looks like it is solved !
Thanks again,

Denis

PS : will there be a fix in Wheezy so that other Epson stylus photo 
users don't have to face the same problem ?
