I think you misunderstand something (or it's me :-()

You have black and white artwork (china's ink?), not vector graphic one. 
If you scan it it can't be other than bitmap.

A printed 300 dpi scan is visually identical to the original, it's what 
photocopiers do and one can't see any scale on letters

eventually you can go as large as 600 dpi. Other definitions are for 
transparency (diapos) printed or displayed much larger than the original 
size.

If you print the drawing larger than original size, you will see the 
original paper defects, or ink bluring in the paper

you can't really make a vector from a bitmap. You can try with a draft 
of mechanical engineering, with constant thread width and the result is 
ugly. You certainly can't go from inkscape to gimp and vice-versa. The 
best you can achieve is ti have inkscape store your drawing as bitmap...

the only way to make real vector graphic is to draw with stylet and 
table directly in the computer

anyway to print post card, vector graphics is not needed
