You have hit on the key difference between display resolution of ppi and print resolution, but there is an additional point as well:
Yes, the number of dots used by the printer to print the display pixel is set by the print resolution. But further, each printer dot is produced by a number of spots - I recall this being discussed in a chapter of a book I read recently, with diagrams showing the dot-spot relationship, but I don't recall which book. If it comes to me I'll let you know.
