Re: Close..

But, you're right, image will be rescaled upwards to printers
native resoution.

Not exactly if speaking of inkjet-printers.

The printerdriver separates the input to CMYK (or more colours, depending on printer) and produces rasterized data from that (a frequency modulated pattern normally). It then sends the pattern data to the printer. This has nothing to do with upscaling to "native resolution" wich btw refers to the positioning accuracy of the printheads. Printed resolution depends on the size of ink drops and the raster algorythms used and is MUCH lower than advertized.
