My reply of 11 February was a bit premature. Within a day or two, my iMac27 (Intel) stopped seeing my Epson 835 printer. Try as I might I was unable to get it talking to my 835 in either LAN or wireless, even though 2 other computers, and now my little laptop can see it through wireless. So I connected it USB. Only then would my iMac see the 835. Problem is that my wife's computer (Win7) also has trouble seeing this printer in anything but USB. So, I now have my iMac and my wife's Win7 connected to the 835 through a USB switch, one or the other, but not both simultaneously. It's a workaround situation, but no hiccups for past month.
Like many iMac Lion owners, I too am having all kinds of trouble getting it to work with peripherals, like 3 scanners, that still have PowerPC drivers, which Lion no longer supports. My scanner manufacturers advise me they have no plans to develop a new set of drivers for Lion, not nice at all. I'm regretting ever upgrading to Lion, and am wondering how I might be able to migrate back to Snow Leopard without a whole new install.

Terry
