another one here with the same problem.

I did find a registry fix, but i'm afraid to try it.
here it is:
Hello People, I had the exact same problem on several
machines running Windows XP /Pro & Outlook 2003.
I export the below reg key from a W2K machine with Office
XP and imported into the XP/2003 machine and it has fixed
the problem.
Thanks for the post & the information.
Regards

I have had the same issue with printing HTML. I was
receiving the preview.dll error, and line 1341, error. I
did apply an update to Office 2000 that was not
installed, and this stopped the error, but I still wasn't
able to print HTML from Outlook. The following registry
key was missing from my system.
The following is a repost of a solution that was posted
by Gary Van Der Hart on Jan 27th. I checked to see if
this registry key was missing, and it was.
I went to another pc that had this and exported/imported
to mine, and that solved my problem.

===================
After going through all the links trying to find out why
that Line 1344 Script Error kept me from printing either
in Outlook or Outlook Express, I finally called
Microsoft. They scheduled a second level call to me and
after a few things to try, the solution was that a
critical registry key was missing. There is no
explanation why it was missing, but I was able to
recover it from another machine and I am back in
business. Absolutely amazing after many months of torture!
Here it is, but I'd find the key from a reliable machine
and get a quality copy of the file to keep from
destroying your system...
This is from a W2K Pro OS.
