    Improve printer distinction for option retrieval
    
    In order to retrieve the user options for a printer, the respective
    printer name is used.
    This fixes the comparison of printer names to avoid that the options of
    another printer are accidently read whose name starts with the same
    letters, but is longer (e.g. "myprinterlongername" instead of
    "myprinter").
    
    This fixes Bug 753628.
