OK. I got the grid to "print" out by making the scale 60% and doing a Save As... to PDF.
Under Print Settings/Printing options... I also set the top margin to 0.5 inches, and the top margin decreased, but the issue we see with printing is not caused by this setting.
I trued printing the document physically, as well as doing the pdf preview, and I saw that the top margin was even bigger and the graphs were still cut off in the same way. It looks to me like the Mathematica Print engine is hosed.
Setting the scale to 40% and trying to print in Portrait mode results in more of the image being cutoff horizontally and an even larger margin at the top.
The attached file is the Save as PDF at 60%, landscape mode that works.
I will file a bug report.
