On the Mac I am aware of how to do a screen capture, but it creates a 72 DPI image. We need a much higher quality image because it's for printing on a color laser printer. We need to be able to print this out high-quality so it looks good on a 11 x 17 inch paper. Thanks!

    It creates a 1:1 capture of your screen resolution. – Ruskes Jun 7 '13 at 3:10
  • Any way to improve the quality so it looks sharper when printed? Or is there another method than doing a screen capture? Kind of like Print to PDF, but Print to higher quality TIFF? – Edward Jun 7 '13 at 5:49

Taken from here.

defaults write com.apple.screencapture type pdf
killall SystemUIServer

Several other choices besides pdf and default png, see link.

  • Can this also capture the entire screen, like from a web page even if it requires scrolling to see the entire web page? – Edward Jun 7 '13 at 7:18
  • You mean, with live scroll bars? No. – Andrew Lazarus Jun 7 '13 at 16:34

If you run sudo defaults write /Library/Preferences/com.apple.windowserver.plist DisplayResolutionEnabled -bool true and restart, the Displays preference pane will include settings for HiDPI modes:

You can save a screenshot of an entire website with webkit2png:

brew install webkit2png
webkit2png -F http://apple.stackexchange.com/questions/93321

-F only saves a full-size screenshot. webkit2png uses a HiDPI mode when a HiDPI resolution is selected from System Preferences.
