PDF printing with sections missing

Can you print the PDF as yourself whilst logged into her machine or another one? Has she tried printing the document off another machine which will then narrow the problem down to be local on the machine.

Try uninstalling and then redownload and install adobe and see if you helps.

I can print the PDF fine from any computer, including hers.

Right,

I believe the issue is with her local profile on the machine. Log her out and then rename her local profile to usersprofile.old and then log her back in and try again

Can she print it, but to a *different* printer? - if still bad, it would point to the doc, or the configuration that she has for it inside Acrobat, or possibly her printer setup.

Is she printing from the full version of Acrobat (not from inside a browser window, for instance) - that gets a bit cheap and nasty sometimes...

I would look at printer settings while she's logged on. It could be that some printer preferences specific to her profile are at issue.  If re-adjusting settings in that printer preferences dialog doesn't fix it, you might need to clear her profile if other people can print that same document on the same printer from that computer.

Is the PC Windows 7?  If it is, then renaming the local profile folder is a bad idea in Windows 7.

Windows XP would be OK with that:  if it didn't find the local profile folder, it would just create a new one.  Windows 7, on the other hand, will kick up an error that the local profile folder can't be found & will load the user into a temporary profile.

To clear out the local profile using Advanced System Settings:
1.  Log her off
2.  Log on to the PC using an Admin account
3.  Make a copy of the local profile folder (say to C:\Users\UserName-COPY).  
4.  Right click on the "Computer" icon in the start menu or on the desktop
5.  Click on "Properties" to open the System Properties
6.  On the left side, click on "Advanced System Settings"
7.  Then, under the "User Profiles" section of the Advanced tab, click on Settings
8.  Scroll down in the list until you see her user account listed, single click her user name to highlight it
9.  Click the delete button

If you don't have roaming profiles configured, you'll have to restore her profile settings manually:
1.  Have her log back on & open Outlook, configure her account
2.  Once her mailbox contents have populated again, close Outlook
3.  Copy the Signatures folder from the Copy of her old profile to the new one:  C:\Users\username\appdata\roaming\microsoft\signatures
4.  Copy the following folders over from the old copy to the new profile:  Favorites, Desktop & Documents, Music, Pictures, etc. (wherever she has any content)

If she has Office 2007 & earlier, you'll have to copy the NK2 file to restore her cached email addresses (those are the suggested addressees that pop up when someone starts to type a name or email address in the To: field of a new email).  
The location varies depending on the version of Windows & Outlook.

None of the supplied solutions worked, but this work around did.
