a reasonable print? - yeah i don't know how to explain.
Maybe smtg like
"if the screen shot width and height is the half of the SC screen (maximized)
then the 'normal' print out should use the half of the paper too".
i.e. the 'normal' print out should print in a size as the 100% screenshot preview is big.
(If the screenshot is bigger than the SC screen, than 'autofit' it and print this on an paper)
{just an another idea is to print larger shots on two papers, but that's an other story}
I know there is dpi and resolution, DIN A4 and letter too, i have no glue how to code this.
wrt your hint... 'cus of the small print preview i don't see if the quality is good enough.
Is this understandable?
