That is what I want to know. Thanks. I will ask about what fonts are on the
customers computer. Looks like the issue is in the .doc to .ps conversion.
Thanks very much. I thought that font was embedded in the file. In Word there's
a little box in the "save" options that's checked saying fonts are embedded.
But that's my issue.  Thanks again!
