The Epson 3800 6.11 driver is already available from Epson UK as are the drivers for the 4800, 7800 & 9800. Epson US hasn't posted them yet. But the 3800 drivers from the UK work fine in a US 3800.
And some of us have been using them "for a while"...
Jeff, when I have a set-up that works - seemingly - just fine, I'm always a little apprehensive about tinerking with it unless there is some obviously good reason to do so. Now that CS3 10.0.1. is working so nicely with Epson driver 5.51 (Windoze), I'm curious to learn from your experience what would be the incremental benefits or risks of changing to version 6 drivers (4800 and 3800)?
