+// mPreparingForPrint - indicates that we have started Printing but

+//   off right before we go to the timer.
+//
+// mDocWasToBeDestroyed - Gets set when "someone" tries to unload the document
+//   while we were prparing to Print. This typically happens if a user starts
+//   to print while a page is still loading. If they start printing and pause
+//   at the print dialog and then the page comes in, we then abort printing
+//   because the document is no longer stable.
