Re: filmscanners: pixels, printer dots, etc



Ken--

With a printer you never get to directly specify the number of dots 
it uses to print an image.  Rather the print driver will decide how 
many dots to use based upon the image you give it.  In your example 
the image specifies that each pixel should print such that it 
occupies a square 1/5 of an inch on a side so that's what the printer 
will give you (as measured by a ruler on the paper) using as many 
dots as it needs to accomplish this.
