Is there a simple FAX sending program for Ubuntu?

[Chris Green]

My all-in-one-printer is getting decrepit and it's FAX sending ability
is broken.

I have a FAX/Modem I can put in my system but I can't see any FAX
program that looks as if it will be simple[ish] to install and run.

The ones I have found are:-
    efax - only sends text and postscript files, messy to send scanned images
    gfax - frontend, looks OK, but what does it use to drive the FAX?
    hylafax - much too big and complex

Any suggestions anyone?
