Let me stick with the Epson Stylus Pro 3880, that I know quite well. I'm going to simplify a bit and I'm not going to be pendantic and will refer to black as a colour, even though it's not. There is a difference, but the image pixels map to the printer pixels quite nicely. But the file itself won't get a property as dpi. And if you want you can resize the image. In your editor you can calculate what dimension your image will get when viewed at a certain resolution.

If we do not apply the native resolution at the time of scaling the image, interpolation will occur both in the PP image resizing operation as well as when the image data flows over to the printer and the printer driver is used.The file has a dimension of x by y pixels. If we stick to the native resolution of the printer when scaling, the interpolation of upsampling or downsampling will occur only once, int the PP software. When we print, we have to set the image size as well as the scaling factor when resizing the image. The Photoshop and Lightroom setup screens both require the dpi to be entered. HP and Canon printers have a native resolution of 300 dpi and Epson printers have a native resolution of 360 dpi. The dpi is a scaling factor and it has to be considered in when sizing the image for printing. Actually George, this is not correct when it comes to printing.
