WorkCentre 4250 - Fax From PC Issues

Hi,

We are a Xerox re-seller and a small IT company with multiple service contract clients

One of them has a WorkCentre 4250 printer from which they send faxes from.

Client has been printing the document to be faxed then sending it via fax

Wondering if this printer has the ability to send faxes directly from the PC through the printer

I have noticed that other WorkCentres have a PC-Fax utility

Any help on this would be greatly appreiated. 

Thanks!
