In my opinion, no, because it sort of breaks the idea of auto-printing.....there shouldn't be any user interaction required. For my particular usage, I need to focus on what I am working on and just press the hot key. (In my case, I develop web apps and sometimes need to navigate around a UI and take screenshots for reference. You can imagine how tedious that would be if I had to go to a page, then stop and click a button in SSC, then go back and repeat).
In an ideal situation, there would be a button to set autoprint settings that would be separate from the normal (manual) print dialog. I could even set a different printer. For example when using autoprint I might want to take a large series of screenshots to be sent to a PDF creator, but normally just print to my laser printer when doing it manually.
But as a minimal solution, it would be nice just for auto print to use the existing print parameters (esp margins).
Thanks for looking at this
