// 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.
