Late but quite welcome.

I am embarrassed that I missed this obvious point.

Touche' Stephen and thank you for this correction.

Yes indeed (missed that too). However, IF you print and let the driver handle this sizing (as I suggested), then there would be a difference at this point. At least for Epson printers, just set the size you wish for the print, leave the resample off of course. IF the values fall within 180-480ppi, let the Epson driver print at that size (in this case letting it ‘resample’). I would not go below 180ppi and above 480, the image quality can sometimes degrade depending on where you are doing the printing (Lightroom is a difference case). But if the print size is what you want, and the PPI is 181, 187, 203, any value, just leave it as such, let the driver give you the print size you asked for.

The metadata that Stephen talks about is detected by the print driver which can resample to the size one asks for.

It would still have the same amount of pixels as it originally did. You would have to resize from 180 to 300 in Photoshop with resampling turned ON. Then you would have the same final amount of pixels as the PR7 interpolation. Then the question would be how much better are the new pixels from each program and how do these pixels look in the final output/use? Regards, Stephen Marsh

Thanks Stephen!

That makes tons of sense and is a direct answer!

You're right...it does beg the question: "how much better are the new pixels from each program and how do these pixels look in the final output/use?"

Best,
