I am not able to download a software & driver to install this printer on my mac. HP website tells me to download the software & driver provided with my operating system. Apple tells me "Can't install the software because it is not currently available from the Software Update server." Is it possible to get a link to download the driver/software from HP? Software is OS X Yosemite version 10.10.5. Thank you for your help, I don't want to have to buy a new printer!
