I just brought home an "Epson WorkForce WF-2540" "all-in-one" printer/scanner to use via wifi from various Linux and Android machines in the house. Unfortunately, since Apple gave CUPS the heave-ho, specs in CUPS from manufacturers for new printers seem to be lagging. After extended experimentation (misled by anti-clues in macosix drivers), I find that telling CUPs you have an Epson "Workforce WF-845" seems to work OK. This probably is true for the new WF-2530 as well. This seems like a pretty mature device. It has a USB "device" socket and an RJ45 ethernet socket for if you don't have wifi, and a USB host connector, apparently for talking to your camera or USB memory stick. I haven't tried those, or the scanner.

This being the eve of the election, there's just one thing I'd like to hear at a debate: "If you have to lie to make your case, what does that say about your case?"

The best deal on a webcam/mic I've found lately is a "Gear Head" WC740I (or just maybe WC7401) "Plug-n-Play 1.3 MP WebCam for PC" for $15. It worked immediately when I plugged it in, using the standard UVC driver, no fooling around. I don't know how common this is, but it has a mirror ring around the lens so you can tell if it's pointed at you.
