I just attempted the install of Printao8 Home edition to use with two Epson printers - the SC-P600 and the R3000. Adding the R3000 printer went fine, but the 600 did not. Two instances appeared to add, i assumed one was for Airprint and one for USB. I will spare the gyrations i went through but at the end of the day all of the Signature Worthy profiles were missing. The Legacy profiles didn't exist, but i assumed those papers may be too new. Since i prefer Exhibition Fiber at this point for Black and White, missing that profile was a problem. I called Tech support. Their tech support is in Germany, which was not an issue. I stumped the fellow intitiallly, but he did more research and called me back. He was surprised that those profiles were not available and had to be loaded as customer. My only option was to load a P800 profile, which was successful, but only provide a draft quality option. The tech guy tried to assure me that it would be ok, but it was not convincing. I don't feel like wasting expensive paper to do this. Bottom line for me is that it completely defeated the purpose of this easy printing software i am am sorely disappointed. I give the tech support process 4 stars, and the product 0 stars. I will attempt to get a refund.
Since this software is likely much more valuable to larger format professional shops, those packages may not have this problem. If you are like me an a hobbyist that likes to try new things out, don't waste you money on this.
