LOL, but I haven't seen a MFC that doesn't fax to PC. If you have a fax server in the fax machine, it will fax directly to PDF, and you can print directly to fax as a PDF.
Xerox, Muratec, Toshiba, HP, etc. Brother does the same thing, only as a TIFF file.
I guess if it allows you to fax to PC in a TIFF format & you want the extra hassle of converting them to PDF then those machines are worth one's time & hassle.
Most MFC's have FAX FORWARDING capabailites.I prefer to have my FAXES forwarded in PDF format & that is where you can forward it to your email address.
