LaserJet P2015 Print Options?

I have a question regarding setting the 'Print Quality' for a HP LaserJet P2015.
Under Windows 7 Pro 32-bit, I have installed the following 5.8.0 driver, UPD Version 5.8.0.17508, 61.160.1.17508:

• HP Universal Printing PCL 6
• HP LaserJet P2015 Series UPD PS

I have read the you should be able to select between:

• 1200 dpi (ProRes)
• 1200 dpi (FastRes)
• 600 dpi
• EconoMode

However, I can only choose between 600 dpi, Best or Standardprinter.  How do I configure the printer to be able to use the 1200 dpi options, or have these print modes been removed from the latest drivers?
