<h2>enable print</h2>
<code>enable print <i>fname</i></code>
<p>
This command opens the output file <code> <i>fname</i></code> that will contain the instructions in GrADS metacode format to create a hardcopy of the graphical display. Any existing contents of <code><i>fname</i></code> will be lost.
The output file <code> <i>fname</i></code> is referred to as a GrADS metafile.
<p>
<h3>Usage Notes</h3>
<p>Creating a GrADS metafile for vector-graphic hardcopy involves four steps:</p>
<p>1. Open the metafile with the <code><a href="gradcomdenableprint.html">enable print</a> </code> command<br />
2. Create the graphical display that you want to print<br />
3. Issue the <a href="gradcomdprint.html"><code>print</code></a> command. For multiple images in your metafile, use <code><a href="gradcomdclear.html">clear</a></code> and then <a href="gradcomdprint.html"><code>print</code></a> again.<br />
4. Close the metafile with the <code><a href="gradcomddisableprint.html">disable print</a> </code> command</p>
<p>After you have created a GrADS metafile, you can </p>
<p>1. convert it to postscript using the external utility <code><a href="gradutilgxps.html">gxps</a></code> <br />
2.
convert it to encapsulated postscript using <code><a href="gradutilgxeps.html">gxeps</a></code> or you can <br />
3.
display it using the external utilities <code><a href="gradutilgxtran.html">gxtran</a></code> or <code><a href="ftp://cola.gmu.edu/grads/gv/gv32.exe">gv32.exe</a></code> (for MS Windows)</p>
