Well, I found
this GDI-driver, which was originally written for the HL-720 series and is listed for this fax, but I guess it is in german and since it is labeled w95 I highly doubt it will work with XP or even Vista... if that doesnt bother you, feel free to try it :)
Anyway, as almost any Brother fax this model was built on top of an existing printer, in this case the
HL-1030... one of our sales guys still uses this model with WinXP, so you could download drivers for this printer and try to use it with your fax, it might just work :p
Ah, egypt, the place where I spent my childhood... Greetings from germany :D
