I hope you know what you are talking about. The Epson 7800 Stylus Pro is an Ink printer with 2880 x 1240 dpi. Thats still 3,5 Mp. Still 1/10 of 36Mp. and ink technology. Photoprints are usu sally made with LASER or LED printing and they are about the same quality. For true quality you should have "7360 x 4912 dpi to see your true image resolution."

Not true. DPI is indeed the printer resolution (2880 x 1440 dpi; 1440 x 1440 dpi; 1440 x 720 dpi; 720 x 720 dpi; 720 x 360 dpi; 360 x 360 dpi), but the image is sized and sent in PPI (Pixels/Inch) with software and sent to the printer.

Most software programs that I know about, like PS CS6, use p/i. The printer then converts to its native resolution, or 360 p/i in the Epson case. Even multiples pretty much produce identical results. 720 p/i looks the same as 360 p/i . . . as does 240 (2/3 of 360). Tested more than once!
