I'm not sure I understand the question, or the answer by Mr. Wolf.
I believe the question is really about resampling and the algorithm controlling it. My attitude in printing is, if possible, do not resample; print all, and only those pixels in the original image. This means choose one of the canonical Epson resolutions (1440, 720, 360, 288, 240,…) that will result in ppi = dpi. That is, all and only the original pixels will be printed.
For instance, if the long dimension of your image is ~5500 pixel, then choosing a resolution of 360 dpi will result in a print that is 5500/360 = 15.278 in, and if the image has not been cropped, you'll get a print of about 15x10 in.
Do the math; it's straightforward. Of course, you cannot avoid resampling if you constrain both the printing resolution and the print size together.

Re: [QuadtoneRIP] resizing

You understood the question quite right. I'll do the maths and use resizing only if needed and in Photoshop. I never upsize any print. Actually I have more than needed for the size of my prints so I just wanted to know if someone knew the difference between Photoshop, Genuine Fractals and QTR as far as algorithms are concern.
Thanks for your answer
