There are a few operations there, sometimes separate, sometimes linked.

Cropping is often for composing your image, although can be for trimming excess
off. Set the crop tool to a fixed aspect ratio and apply. That loses part of the
image.

The result can be set to size for printing in Image -> Print Size. This does not
change the pixel size of the image. The required size and  pixels-per-inch (ppi)
value are saved with the image (metadata) and used by the printing software (or
should be).

If you want to set a different ppi with a defined size  then scale the image.
Image -> Scale Image. This will change the pixel size of the image, depends how
much scaling, and can lose detail. A modern camera image should not be a
problem.

No videos? Here is a short, 5 minute demo of the above.

This is Gimp 2.10 - just using a light theme and adjusted toolbox - makes easier
viewing as a video.

Also included adding a border to fit on a defined paper size. Some print
franchises totally ignore the image metadata and will fit an image  to paper
size no-matter-what. A border can circumvent that.

PS. You should not need to add an image to post here. Also. You have chosen a
terrible forum for detailed replies. Top posting / bottom posting /
quote-after-quote.... For pure photography then try  https://discuss.pixls.us/
and there are a couple of other dedicated Gimp forums if you search.
