Nope, sorry.  What you're asking for there is a Class 3 feature.  
Class 2 handles all of the fax protocol negotiation for you, but the 
computer still needs to convert the data to CCITT T.4 compressed 
image format itself.  Class 3 is envisioned to include data 
conversion functions in the modem, at least for transmission -- 
things like text, PostScript, Epson emulation, HPCL emulation, etc.
