Windows 7 + Acrobat + Xerox – half-page reduction problem

Does your Adobe Acrobat/Reader always print on your Xerox Phaser 8550 (or other Xerox) with half-size output locked into landscape even when you force orientation to portrait? An illustration will explain the problem better:

It appears that this is a legacy driver problem. Here is the fix I used:

  1. Goto Devices and Printers → remove the offending Xerox printer!
  2. Goto the Xerox website → download the Xerox Global Print Driver (dated 9-Nov-2012 at the time of writing). Make sure it is WHQL certified.
  3. Select Install from Web.
  4. Delete the old drivers → highlight another printer → click Printer server properties at the top of the Control Panel window
  5. Click Drivers → highlight your Xerox driver(s) → click Remove → select Remove driver and driver package.
  6. Reboot.
  7. Run the set-up program (in my case Setup.
  8. The set-up program should detect your printer which you should then select and click Next.
  9. Select your required option(s) and click Install (I chose Postscript).

Thank you to those who took the trouble to post their solution in the Adobe Community.
