I also fax right from my exam room computer. I have a Brother MFC 8840D machine which is networked (via Jetdirect) and it works beautifully. My scripts are not signed. But, I had been printing the scripts for over a year, signing them and sending the patients out with them. I think most of the regional pharmacies have become quite familiar with my script format so, when they began showing up over their faxes, it did not phase them. I also sent each pharmacy a test script fax which explained what I would be doing and asking them to fax me back it if was received and if there were problems with the format. So far, not one complaint. Since I am in Indiana I still have to write my scheduled drugs on a special script but otherwise, being able to fax directly is a great time and paper saver for me.
