I admit it is a shame that the lost dongle incurs a new license fee. One would think that Colorbyte could verify a dongle use, since each one has a unique code. Having said that, I have to say that I have used the Image Print ver,10 for the last 6 months now, and the results are fantastic. There is nothing like their output sharpening, which uniquely sharpens the final image going to the printer in a way that I cannot match in Photoshop. I don't know all the technical details, but apparently the sharpening of the print file on the way to the printer is different in some unique way that cannot be matched in the sharpening of the image in Photoshop.
If I don't use Image Print 10, and print only with the Photoshop/Epson print profiles, even after downloading the paper profiles from the manufacturer, my pictures seem anemic, and less sharp.
The ColorByte program also saves a great deal of time with paper print errors and size mismatches.
My wish is that the program would become more affordable in the future, so more photographers could try it out.
