Fax via USB or Bonjour connected Brother 7820N MFC

Question

From what reading I have done this should be possible, but the OS does not see a fax machine. The Brother MFC 7820N is on Apple's list http://support.apple.com/kb/HT3669#brother as having fax driver support. The relevant section appears to be thus:
"Scanning and sending faxes with multifunction printers
The software available with Snow Leopard may allow you to scan or send faxes when using a multifunction printer. To see which features are available for your printer model, find the model in the list below. In the columns next to the model and software version, you will see a "Print" if the software supports printing to the model, "Scan" if the software supports scanning with the model, and "Fax" if the software allows faxes to be sent (through the Print dialog in applications) with the model. If your printer has a feature that is not available with this software, contact the printer manufacturer for more information regarding the use of that feature.
The steps needed to send a fax from a multifunction printer vary from model to model. With some models, you will have a two printers added to your printer list with similar names, but you must select the one with "Fax" in the name when you want to send a fax from the Print dialog. With other models, you will find the fax settings in the pop-up menu in the Print dialog (the same pop-up menu where you'll find the settings that are specific to your printer). Contact your multifunction printer's manufacturer or visit their website if you have questions about sending a fax from your specific printer model."
The problem is the OS does not see the existence of the 7820N as a Fax machine. I have all the latest drivers.
Any suggestions as to what I might be missing? Do I need third party software to even see it as a fax?

Answer 1

I found my answer with a support call to Brother. The "Fax PDF" choice in the lower left of the print dialog box is ONLY for use with a fax modem, and the MFC 7820N (and possibly other printer/scanner/fax machines) will not show up as a fax target in the system preferences | print & fax | add printer | fax choice. To use a multi-function printer you must the pull down menu in the print dialog directly under Orientation. Change the default selection, which will generally be the program you are printing from, to "Send Fax" and proceed.
I hope this helps other users.
