Basically no, but sometimes yes. In my 3800 if you choose Ultrasmooth Fine Art Paper, you will presented a new (old) choice 'Printable Area'. The choices are Standard/Centered/Maximum. The default is Standard which gives you different left and right margins/borders.
(Old: if I remember correctly, this choice was present in all Epson drivers some 5 years ago).
I dont know why Ultrasmooth Fine Art Paper has this choice. And I dont know if the above is true for other Epson drivers than 3800.

If interested look at threads in the Qimage area (Unequal borders/ Different borders). I still dont understand why Qimage does not include the Epson hardware borders when defing the Qimage margins. Now I think I can manage the margins/borders, but I have to calculate the print locations parameters in Qimage myself.
In the same area there is also a thread called "Centering 7900 sheet prints".
