Bug introduced in 10.0 and persisting through 11.2 or later
I have two problems with printing in version 10.
First, I can't print correctly with a setting of printing scale
For example, I have some plots in a notebook,
Grid@Table[ Plot[Sin[x], {x, 0, 2 π}, ImageSize -> Medium], {4}, {4}] 
when I print with scale 70%,

I get something like

I always get a big blank at the top of the page, no matter what I set the margins in the printing options dialog.
Second, the curve seems to be stretched after print.
Here is compare between screen shot of the figure in the notebook and after print

You can see that the curve in the printed version stretches out beyond the frame.
Are there ways around these problems? Currently I have to switch to older version once I need to print something.
The example notebook is here
I'm using 10.0 for Mac OS X x86 (64-bit) (June 29, 2014) on OS X 10.9.4.

PlotRangeClipping. And I only see it when the page orientation is landscape, not portrait. I would say this wrong clipping is a bug. The other printing issues with the space and the plot not fitting on the page are very annoying and long-standing problems that I don't have a good general solution for, either... except to export plots one at a time instead of printing the notebook. $\endgroup$
