So you're saying if I get a page size that is more than 72x8.5 by 72x11 then I could be printing at a higher DPI? And you're saying the page size that's returned may not exactly be 72x8.5 or 300x8.5? I'm guessing that would be because of the margins and options the user chosen in the print dialog. I'll have to check.
But that means by the time the user finally presses the print button on the OS print dialog the DPI is set in stone. That's when we get to add and scale the display objects we want to print. It sounds like then if I scale the display object after getting the page size information it won't change the DPI of the actual printout but will give me enough information to know what it is. The way I've been testing this is by choosing the Open as PDF option in the print dialog but I think I'll have to do some print outs. Do you know why certain things like Button would not look correctly in the printout? It looks like the button was vectorized (actual graphics data or commands were used) but not all of them. for example, the button has a thicker border than normal and it's label is text selectable but the button background is missing. in the PDF the button scales up as a vector would. does ui component bitmap capture highlight have anything to do with it?
