Updated to 21.0.1432.57 and suddenly when I print checks from my banking application to my pdf print driver the checks come out blank in the pdf file. Did a system restore via Windows 7-64 to 20.0.1387.91 and all is well again. I also printed some web pages to a laser printer and got some strange text (not english) and this too reverted once I rolled back. Printing seems to be the weakest link in an otherwise great browser.
