The scanner can scan in different resolutions.
A printer can print in different resolutions.
The display can also have a resolution different that the scanner or
printer.
Various application programs and printer add ons to such things as a browser
can automatically scale.
On my system
Display 1280 x1924 (LCD native) (an often used DPI for displayed text size
is 96)
Scanner 200-300DPI for general use and prescan, much higher for small items
such as slides, negatives, and stamps.
Printer (Ink Jet) ~200-300 DPI normal use, ~720-2400 high quality picture
printing, (Driver does dynamic scaling, based upon multiple factors)
Fax (all in one) Standard & Fine Fax resolution, higher between two units of
the same make and compatable models.
I can optionally set the printer driver to scale or not to scale if I want
to enlarge or reduce the image to an 8 1/2-11 page.
Commonly used photo oriented apps allow an image to be resized by the number
of pixels in the image file, and/or the number of pixels per inch.
In other words, you will need to change settings. Which ones depend on what
is most convenient for your exact usage.
