The new driver for the 3800 may be the equivalent to the new driver for the 7880 for which the numbers are versions 6.12 and 6.55. That is available also only on the UK, Australian and New Zealand Epson sites. I downloaded it recently and because ABW did not work with version 6.12 (as acknowledged by Epson), and the newer driver does. There are a few very minor differences otherwise. No problems with the new driver, in case of the 7880, and the ABW functionality is a big plus.
I have now the printer twice in the dialogue box, with either driver, but will delete the one with the old driver.
