Apparently this is a permissions problem. I think I caused it by installing separate HP drivers (messy business), instead of just using Apple native ones.
More importantly, this isn't a Pages problem or a font problem: as far as I know, ANY program you try will not not be able to print to PDF or actual printer.
In any case, I found the solution on google groups. The distilled instructions are simple:
1) Go to Disk Repair Utility
2) Click "repair permissions" (take a few minutes; may generate a large log of corrections)
3) Restart computer (don't just logout!)
Some others on Google groups had a more difficult time (the above procedure fixed mine). So if for some reason that doesn't do it for ya then check the discussion below for more info or search google groups under the same error phrase.

More information:
If disk repair doesn't totally fix your problem, try the "repair disk permissions" option on an excellent tweak program called "cocktail." (

Their documentation on this issue (see their help file for more) is as follows:
"Mac OS X incorporates a subsystem based on a UNIX-style operating system that uses permissions in the file system. Every file and folder on your hard disk has an associated set of permissions that determines who can read, write to, or execute it. Incorrect permission settings may cause unexpected behaviour, for example, applications are appearing in the Dock as question marks and/or are not able to connect to the Internet, software installed while logged in as one user will be inaccessible when logged in as another user, files created in Mac OS 9 may appear in Mac OS X with root ownership, backup software may not back up Mac OS X system files that have root ownership, folders for which you do not have write permission can end up in the Trash and you will not be able to delete them or the files contained in them...When you repair disk permissions, the system reviews each of the “Bill of Materials” files in the /Library/Receipts/ folder and compares its list to the actual permissions on each file listed. If the permissions differ, they are corrected (all modifications to the privileges will be lost)."
