Suppose you have a short document (including a fancy header) which occupies only a small part of a DIN A4 page, like in this example:
\documentclass[a4paper, 12pt]{article}
\usepackage[top=2cm,hmargin=2.2cm]{geometry}
\usepackage{fancyhdr}
\pagestyle{fancy}
\fancyhf{}
\fancyhead[R]{\small \today}
\fancyhead[L]{\small header}
\fancyfoot[C]{}
\begin{document}
short text short text short text short text short
text short text short text short text short text short
text short text short text short text short text short
text short text short text short text short text short
text short text short text short text short text end of the text.
\end{document}
Suppose I want to print this text 50 times. To save paper I would print it and use a photocopier to copy this text incl. fancy header several times to one sheet of paper.
Now my question is, if there is a simple LaTeX way to do this, i.e. in the above example, have as many copies of all text from fancy header to "end of the text" automatically on a DIN A4 sheet as you can fit on it?

\\in the text, I get endless stream of errors given below ... see removed non-answer – Tem Pora Nov 24 '12 at 06:56
