Background

I replaced som XP computers with Win 7 computers. We have a HP Laserjet 1320dn printer attached to the LAN. The XP computers could print to it from Word in duplex mode without any issues.

Problem

The Win 7 computers downloaded a full set of drivers including a "HP Laserjet 1320 PCL5" driver. However using this, Word's page footers cause extra pages to be printed with just a letter or so at a time from the footer. Some other apps have similar issues.

I also have an ancient Laserjet 1200 attached to the LAN via a Jetdirect box and that works just fine. So I don't think the problem is with Word (the computers came with Word 2010 starter).

What I tried

I wrangled the control-panel new printer dialogue into using a "HP Laserjet 2100 PS" driver for the HP Laserjet 1320dn. Now my Word documents print as they should. However I don't have a duplex option on the print dialogue. I'd really like to be able to use duplex printing.

Question

Windows used to have a Universal Postscript driver that read a Postscript Printer Definition (PPD) file to make the printer's features available (tray choice, duplex etc). I can't see any way to do this in Windows 7. Is there a way?

Is there any other way I can get Windows 7 Home Premium 64-bit to print properly to a HP Laserjet 1320dn and have access to all it's major features?

Addendum:

My page in Word looks like this:

+--------------------+
|  aa      bb    cc  |
|                    |
| lorem ipsum dolor  |
|                    |
...
|                    |
|  pp     qq     rr  |
+--------------------+

The headers and footers were inserted using Insert -> header -> blank (3 column).

When printed I get

1 page with aa, bb, cc, pp in correct position (no other text)
1 blank page
1 page with qq in correct position (no other text)
1 blank page
1 page with rr in correct position (no other text)
1 blank page
1 page with lorem ipsum dolor in correct position (no headers or footers)

If I use a Laserjet 2100 driver I get 1 correct page.
