If you are saying that you scan to a PDF then that is entirely 
appropriate if your intention is to produce a small file that a site's
visitors will download and print.

However, in case newcomers are reading, it should be pointed out that 
it is pretty pointless for an image to be displayed on a web page, 
where dpi is completely irrelevant. For screen display all that 
matters are pixels. For that purpose you scale to the desired width 
and height in pixels. Adjusting X or Y resolution (i.e. dpi) is 
meaningless.
