He's right on both counts. Epson has put cart recognition software on the main board to lock third party carts out. The printer actually senses that a genuine Epson cart is not installed and then totally freezes up and you have to call a service tech. It's very serious this time. I don't think the piezo inks bother them so much, it's the cheap color ink out there that really pisses them off. Walker is trying to find a way to refill new Epson carts for the time being. They are asking people to save them. I would definitely use the 9890 for the best and most reliable piezography printer. The 9880 is also excellent but most of them are pretty old now. That is what I've been doing for five years with the 9890 and it is still working fantastic for that purpose. I wouldn't buy a used 9900 though. Wouldn't trust them.

No, at least not currently. Piezography requires using refillable cartridges with chips which can be reset, and Epson has made this essentially impossible in the new Pxxx printers which are sold in the U.S. (I believe Jon and Walker continue to research options, but there are no guarantees at present.) If you want to do Piezography, your 9890 is the ideal candidate for conversion.
