thx for the answer the pb is not my printer or its driver
it is ML !
driver are ready to work, but when i want to connect my MBair to the printer
standard procedure: ip etc
when it comes to a pop up window where i am suppose to choose a driver there is no or better said none
and again my drivers are up to date !
the result is with the generic driver that the printer refuses the file
the printer is connected to my router via usb
