I avoid the possibility of introducing resampling artifacts by unchecking that option in PS/Image/Image Size. This means that when choosing a resolution of 360 dpi, the print size (from an uncropped image) will be slightly larger than 10" x 15". This size satisfies much or my needs - but not all. Not-resampled images printed at higher resolution result in a smaller print (because one is matching dpi and ppi.) So, is it possible to get a larger print, at a higher resolution, while avoiding the artifacts that might be introduced by the resampling algorithm?
Jon, in his manual, states, "In fact, anyone will tell you that anything more than 360 ppi is wasted on the Epson printer driver. But, printing at 1000 ppi with Piezography actually results in significantly more detail. You would not want to add this resolution to the image file by resizing. Resizing is actually less effective as a way to increase the printed image size than simply scaling in the printer driver."
That sounds like I can have my cake and eat it too. But I'd appreciate an elaboration of Jon's statement. How does scaling differ from resampling (resizing*)?
*I'm assuming that resizing=resampling.
