High resolution screen captures
Authored by: gmachen on Apr 22, '11 12:32:16PM

If one Screen Zooms before doing the capture, the saved screen grab is the larger size.
(The [command key of your choice]-two-finger-swipe-upward to Screen Zoom is controlled in the Trackpad System Preference.)

This wouldn't accomplish the same goal, though...

The OP is trying to get more original, precise pixel data in his screen captures so that printing comes out better. The method you're describing just upscales the image before capture, rather than after capture. The algorithm Apple uses in screen zooming is pretty darn good, but it does still introduce artifacts that the OP's method may very well avoid (especially in text and other vector based elements of the screen display).
