Are you a current Epson R2400 printer owner who formerly owned an Epson 2200 and also used the ImagePrint 6.x RIP? If so, did you upgrade/convert your ImagePrint license for use with your new 2400? If so, what was your motivation?
I used ImagePrint exclusively with my 2200. It produced, by any measures, the finest fidelity of prints I could achieve with that printer.
But having recently switched to the 2400 with the new K3 inks and new Epson driver I'm finding that the quality of prints produced natively easily meets or exceeds the results with the 2200/ImagePrint combination. Admittedly I print almost exclusively on Epson papers, although I also do some Legion papers. Yes, I know ImagePrint offers an extensive range of paper profiles. But I'm having a hard time justifying upgrading to ImagePrint 6.1 for the 2400. The printer seems to be doing just wonderfully all by itself (and more conveniently than with an external application, particularly one as awkward as ImagePrint). ImagePrint's version for the 2000 series printers always seemed a bit user-hateful and sneering to me. If you happened to try to use one out-of-bounds feature it would silently punish you by ruining your print with "DEMO" watermarks. I always thought that this was really malicious.
I asked this same question at FM but received no response whatsoever. I'd welcome others' experiences and thoughts on this subject.
