\label{output}

A \TeX\ `output driver' translates a DVI file
into instructions for a printer or other output device
(such as a graphics screen).
There are drivers available
for virtual all devices.

\TeX\ drivers generally have names
like \verb"dvixyz" or \verb"dvi2xyz",
where \verb"xyz" is the start of the printer's name.
To print the \LaTeX\ file \verb"test.tex"
it must first be ``\LaTeX-ed'' with the command
\begin{verbatim}
      latex test
\end{verbatim}
and the resulting DVI file \verb"test.dvi"
then sent to the printer with a command like
\begin{verbatim}
      dvixyz test
\end{verbatim}

The following \TeX\ drivers are available
in the School of Mathematics.

\begin{description}
\item[dvifuj]
This is the program for printing \TeX\ or \LaTeX\ files
on the Fujitsu matrix printers
in the Terminal Room (School of Mathematics Room 14)
and the Barron-O'Reilly room.
To print \verb"test.dvi" on the former, give the command
\begin{verbatim}
      dvifuj test -Pwr14
\end{verbatim}
For the latter,
\begin{verbatim}
      dvifuj test -Pbor
\end{verbatim}

\item[dvips]
This will send output to the Apple LaserWriter
in the Secretaries' Office.
It is presently reserved for staff and research students,
though it may be made available for special requests,
eg for printing CV's.
The command
\begin{verbatim}
      dvips test
\end{verbatim}
will send the output from \verb"test.dvi" to the printer.
(The `ps' is \verb"dvips" stands for PostScript.
There are many PostScript printers like the LaserWriter;
\verb"dvips" will produce output for any such printer.)

\item[dvi2tty]
This will attempt to display \TeX\ output on a dumb terminal.
It is of necessity very crude,
but can be useful as a first view.

\item[xdvi]
This sends \TeX\ output to an X-terminal
or Unix workstation,
and gives a highly accurate representation
of the printed output.

\item[dvielq]
This produces output for an Epson LQ printer.
