Usually this means that network scanning doesn't work and faxing doesn't work. It would mean that Epson doesn't support those features on 10.8 - i.e. It isn't that those functions aren't support 'by' 10.8. Can anyone point me in the right direction? Much appreciated! In researching compatible printers, the fine print for the epson 3520 states that 'some functions may not be supported by 10.8 OS.' Before I invest, I would like to find out which functions those might be.
