1200 DPI Scan Integrity

Lets say you scan a 10"x8" page @ 1200 dpi
Your image is (10x1200)x(8x1200) pixels
=12000x9600 pixels
The image now has size in pixels only, the dpi is irrelevant.
Gimp can a store a dpi value, but it is dormant until you print on paper.

If a stamp is 1" x 1.5" in size, once scanned it will have a size of
(1x1200) x (1.5x1200) pixels
=1200x1800 pixels.
Check the the size of a stamp in pixels.
If it conforms to the above everything is OK
(and the stored dpi is just a dormant value and won't affect anything.

NOTE:
1200dpi is a very high value for a stamp. It is very unlikely that any stamp has a resolution any where near that.
