# ) becomes 9 in print-out [closed]

I have the following expression \mathfrak{U}^{(\alpha,N)}. The pdf output generated with pdflatex is all right. But the printer turns the ) into a 9. Has probably something to do with the printer driver.

Is there any general way to prevent such things (like \protect or {)} for example)?

Further notes and information:

• I can't test possible solutions since the problem doesn't occur with my own printer and I have no access to the printer in question. Also I cannot provide information about the printer in question. The printing was done in a big copy shop and I doubt whether they still know which printer they used for my document.
• My document has almost 300 pages. The expression \mathfrak{U}^{(\alpha,N)} appears on average once per page. The problem however occurs on only one single page (or so I believe ... impossible to check all).
• I use \usepackage[T1]{fontenc}. Adobe Acrobat however says that there also type 3 fonts in my document, see the following screenshots from the acrobat document properties window (translation: "In diesem Dokument verwendete Schriften" = "fonts used in this document", "benutzerdefiniert" = "defined by user", "Originalschrift" = "original font", "Kodierung" = "encoding")

• Consider the following MWE (compile with pdflatex). Checking the document properties reveals that there are only type 1 fonts. So again, there doesn't seem to be any connection with type 3 fonts appearing in the original document and my problem. As noted above, I cannot check what happens when I print the pdf (with the printer in question).

\documentclass{article}
\usepackage[T1]{fontenc}
\usepackage{amsmath}
\usepackage{amssymb}
\begin{document}
$\mathfrak{U}^{(\alpha,N)}$

Do you use fontenc? –  Juri Robl Oct 17 '12 at 19:00
Yes --> \usepackage[T1]{fontenc} on a WinVista machine (in case that matters) ... should I use something different? –  lpdbw Oct 17 '12 at 19:10
This really seems a printer driver problem. Check the PDF file font properties with Adobe Reader in order to see if some font is listed as Type3. –  egreg Oct 17 '12 at 20:21
I have edited my question taking into account your comments! –  lpdbw Oct 19 '12 at 13:49
Are there included graphics in the same page where the error occurs? –  egreg Oct 19 '12 at 14:06
