Cannot print in A3 from a HP Printer

For the past couple of days, I have been struggling with a HP printer on Windows 7 that refused, no matter the settings, to print in A3 size from Adobe PDF Reader.  

The fix was difficult to find, but easy to implement, here is how:

Go to Printers, Get into the properties of the print. 
Click on Advanced tab
Click on the Print Processor button
Set Print processor to winprint, and Default data type to RAW
