Hi thank for answer but , when I try to use the fax, this is the message in pop up :
I translate for you :
In order to use the printer you need to install the software. To install the software, choose Software Update from the Apple menu. If the printer software is not available in Software Update, contact the manufacturer of your printer.
What can I do ?
It's a loop !
Have you a driver for fax HP Officejet J4580 All-in-One ?
Thank for your patience
Francesco
