Very expiernced at printing with Epson Photo printer for over 15 years. When one prints from Lightroom the native DPI at any given size print (PPI) is 720 when one uses Epson's Photo RPM (highest resolution) mode. Under the same circumstances when printing from a Canon PIXMA iP8720's highest resolution (whatever it is called) what is the native PPI one sets to print from Lightroom?
