Karl, I think you've missed my point. All images, whatever their ppi (correct this time, Austin), printed on Epson inkjets are upsampled by the Epson driver, unless they are already at the ppi which the driver requires (360ppi for wideformat printers and 720ppi for desktop printers) whether you like it or not. So yes, upsampling may always result in some loss, but there is no way of preventing it other than sending your image at 360 or 720 depending on your printer. Since I understand that the printer driver uses Nearest Neighbour resampling - the poorest upsampling method according to many - it might be preferable to do the upsampling yourself with a better algorithm such as Vector, Lanczos, Bicubic, etc and avoid having the printer driver do it with NN.
People who think they are avoiding upsampling by sending their image to the printer as it comes are deluding themselves; the printer driver will upsample it to 360 or 720ppi, come what may. And if sharpening is best done after everything else, including upsampling, by doing the upsampling to 360 or 720 your self you can then do the sharpening as the last thing. Otherwise you have to oversharpen in order to allow for the driver upsampling lessening the effect.
