根据我的回答有哪些方法可以将内容绝对定位在页面上?
\documentclass{article}
\usepackage{everypage,stackengine}
\setstackgap{L}{11pt}
\renewcommand\stacktype{L}
\usepackage{lipsum}
% THESE ARE LaTeX DEFAULTS; CAN CHANGE IF NEEDED.
\def\PageTopMargin{1in}
\def\PageLeftMargin{1in}
\newcommand\atEveryxy[3]{%
\AddEverypageHook{\smash{\hspace*{\dimexpr-\PageLeftMargin-\hoffset+#1\relax}%
\raisebox{\dimexpr\PageTopMargin+\voffset-#2\relax}{#3}}}}
\atEveryxy{7in}{1.8in}{\rule[-\textheight]{1pt}{\textheight}\quad\Longunderstack{ Examiner only}}
\begin{document}
\lipsum[1-20]
\end{document}
