Subject: Bugzilla #44678: Added ability to pass in the PrinterJob instance
 through the renderer options. Submitted by: Antti Karanta
 <Antti.Karanta.at.napa.fi>

Modifications/Additions to patch:
- Don't remove the contructor with the PrinterJob parameter, just deprecate it.
- Adjust old-style print example to use renderer options
