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
