Creating a Signature Line
Unfortunately I have used a table and I hope that I have helped you, also.
\documentclass{article}
\begin{document}
\begin{tabular}{@{}p{.5in}p{4in}@{}}
Approved: & \hrulefill \\
& Fats Domino, Ph.D. \\
& Chair of the Department of Nutrition\\
\end{tabular}
\end{document}
A bit artificial, but doesn't need even knowledge about tables:
\documentclass{article}
\begin{document}
Approved: \hrulefill
\hspace*{0mm}\phantom{Approved: }Fats Domino, Ph.D.
\hspace*{0mm}\phantom{Approved: }Chair of the Department of Nutrition
\end{document}
Six different approaches in no particular order here.
In each case is used a different way of obtain the underline rule and also the left indentation and hanging of the signature.
Note that I avoid intentionally the \hrulefill command since the rule is placed in the baseline, but it look better a bit below (to allow handwriting aligned vertically with "Approved:"), so four of the six outputs are like this one:
Maybe also look better also a pointed/dashed line than a solid line, like \dotfill, but unfortunately (in this case) puts the points too high and scattered, so one approach use a custom \dotsignature rule:
... and other a \dashsignature rule:
Compilable code:
\documentclass{article}
\usepackage[tmargin=1cm]{geometry}
\parindent0pt
\parskip3ex
\pagestyle{empty}
\usepackage{tabto,ulem,booktabs}
\usepackage{textcomp}
\TabPositions{.38\linewidth,.5\linewidth}
\def\dotsign{\xleaders\hbox to .2em{\d{}}\hfill\d{}}
\def\dashsign{\xleaders\hbox to .5em{\_}\hfill\_}
\def\dummytext{\bigskip\dotfill and this text is the very
inconclusive end of the very long report.\par~\par}
\begin{document}
\dummytext
\makebox[.5\linewidth][r]{Approved: }\dotsign\smallskip\\
\hspace*{.5\linewidth}Fats Domino, Ph.D.\\
\hspace*{.5\linewidth}Chair of the Department of Nutrition
\dummytext
\tab\hfil Approved:\vspace{2pt}\tab\dashsign\\
\tab\tab\tab Fats Domino, Ph.D.
\tab\tab\tab Chair of the Department of Nutrition
\dummytext
\hfill
Approved: \parbox[t]{.5\linewidth}{\rule[-3pt]{\linewidth}{.4pt}\par\smallskip
Fats Domino, Ph.D.\par
Chair of the Department of Nutrition}
\dummytext
{\parindent.38\linewidth\hangindent.5\linewidth\hangafter1
Approved: \uline{\hfill}\\[3pt]
Fats Domino, Ph.D.\\
Chair of the Department of Nutrition\par}
\dummytext
\tabcolsep0pt
\hfill\begin{tabular}{lp{.5\linewidth}@{}}
Approved:~ & \\[-3pt]\cmidrule{2-2}
& Fats Domino, Ph.D.\\
& Chair of the Department of Nutrition\\
\end{tabular}
\dummytext
\hspace{.38\linewidth}Approved: \vbox to 0pt{\uline{\hspace{.5\linewidth}}\\[3pt]
Fats Domino, Ph.D.\\
Chair of the Department of Nutrition}%
\vspace{3\baselineskip}% only you type something below
\end{document}
Disclaimer of responsibility: I am too lazy to set lengths with the LaTeX syntax (i.e., I have used \parindent0pt instead of
\setlenght{\parinden}{0pt} and so). I shall not be liable if this burn your brain, your computer explode or something catastrophic happens if you adopt my bad habits.
