We've recently got an EPSON ET-2720. The ink comes in bottles, and it really doesn't seem to use much at all, and the levels are visible from the front.
Obviously it's connected by WiFi and it just worked with both PCs and Macs.
Rumour has it that this printer, like most / all Epson inkjets, counts how much ink has been dumped into the big felt pad, and will brick when it's considered full, which is actually about half full.
