Home Forums Peripherals & Multimedia Peripherals Curious Question Regarding AIO printers

I'm sorry but everyone is missing the point of my question.

I'm not seeking a solution. PC's can fax straight from the computer with most AIO printers. With those same AIO's Mac's cannot do that.

I was just curious if there was something in the Mac OS architecture that prevents AIO's from from offering that same feature. There must be some reason why AIO's would offer that on a PC but not for a Mac.
