I just tested with r73490 and yes the problem persists. I tested also with another page where I generate labels for Fedex and UPS. The page is ftd.com and although the coding there is very IE oriented and plays very ugly with Safari, I was able to reproduce the same error. It seems that it only happens when the page offers a "Print" button, which uses instructions that do not pass the data further to the printing system, however having the label displayed and trying with the proper printing system of Webkit also goes blank. If I try to print normal pages all seems to work ok, so that makes nailing down the bug more difficult. One thing is for sure, it works in all browsers and it works in webkit r73429 and prior. The 2 new builds after that broke the functionality.
I'm attaching here the source code of the page where Fedex generates the label and also a printout from Grab before I try to print and after I try so you have a better idea of the problem. In the source code I see a variable 
var labelImageSrc = "/shipping/labelAction.handle?method=doGetLabelFromCache";
which might have something to do with the problem. Also another strange thing is the iframe wants to load an empty html file.
 Please study the source code and let me know if I can be of further assistance.
