I assume you are considering ImagePrint? I downloaded the trial and spent a good deal of time experimenting (you can do anything the full version does but with text superimposed on prints). I was quite disappointed and in fact surprised. I was comparing IP to prints made on a variety of papers and one canvas with a 7900, all using the canned profiles from Epson or the paper manufacturer and with a variety of subject matter (portrait, landscape, macro). Not only weren't the IP print better than the regular prints, they were not different in any meaningful way. With the portrait, for example, I put both prints in my viewing setup and for the life of me the 2 were, except for the superimposed text, identical. With the landscape I could, if I squinted long enough, see some very subtle differences but nothing that would affect the quality of the print or be seen by anyone other than pixel peepers.
Given the grotesque pricing for IP I really expected more. You can always try it for yourself, but for myself (pretty durned fussy about my prints) I find printing from LR and PS to be all I need, and I use QImage for multiple print layouts. QImage is IMO one of very best deals in photo software. I bought a registered copy about 10 years ago and I still get every update, free.
