  Printing in the Zoo
</div>

<h4>The printers</h4>
<p>
  The Zoo is equipped with a pair of HP LaserJet 4050N printers, one in the
  open portion of the Zoo, one in the closed. They are named, respectively,
  zoo1 and zoo2. See the <a href="/help/etiquette.shtml">Zoo 
  Etiquette</a> section of this help system for some ground rules for printing 
  in the Zoo.
</p>

<h4>Printing from an application</h4>
<p>
  Many document-handling applications, particularly those that run in X 
  Windows, will provide you with a "Print" option somewhere in their 
  interfaces, and will handle the vagaries of text and graphics formatting 
  themselves. All you really have to do is make sure that the correct printer 
  is selected when you hit that big "OK" button.
</p>

<h4>Using lpr</h4>
<p>
  The <tt>lpr</tt> program is the standard method of printing from the command
  line. While its subtleties are many and its workings mysterious, its basic
  usage is summarized below:
  <ul>
    <li><tt>lpr &lt;filename&gt;</tt> will print the file given by 
      <i>filename</i> on zoo1, the default printer. The file may be 
      plain text or Postscript formatted.</li>
    <li><tt>lpr -P zoo2 &lt;filename&gt;</tt> will print <i>filename</i>
      on zoo2.</li>
    <li><tt>lpr -K n &lt;filename&gt;</tt> will print n copies of
      <i>filename</i> on the default printer, zoo1.</li>
  </ul>
</p>

<h4>Printing remotely</h4>
<p>
  <ul>
    <li>On Windows machines, the printers are networked as<br>
  <tt>\\crystal\zoo1</tt> and <tt>\\crystal\zoo2</tt>.</li>
  <li>From Pantheon and other remote Unix servers, print (using <tt>lpr -P</tt>, for example) to
  <br><tt>zoo1@crystal.cs.yale.edu</tt></li> </ul>
</p>

<h4>Format before you print</h4>
<p>
  <ul>
      <li>When printing large Postscript files, consider using <tt>psnup</tt>,
      which fits multiple pages of a document into a single page in a new file.
      Type <tt>psnup -2 file newfile</tt> to do a quick conversion, or <tt>man
      psnup</tt> for other formatting options.  PDFs can usually be converted
      into nice PostScript using <tt>pdftops</tt> (and the process reversed
      with <tt>ps2pdf</tt>).</li>
    <li>Check out the man page for <tt>enscript</tt> -- you can use it to
      convert text files into nicely formatted PostScript, perfect for when
      your professor wants you to submit a hard copy of your source code. Try
      <tt>enscript -r -2 filename</tt> if you're in a hurry.</li>
  </ul>
</p>


<h4>Tips and tricks</h4>
<p>
  <ul>
    <li>Wondering why your job isn't printing? Type <tt>lpq [-P printer]</tt>
      to check the status of the print queue for any of the Zoo printers.</li>
      <li>Just realized you're printing the wrong file / don't like the way it
      looks? Try using the <tt>lprm</tt> command to remove your job from the
      queue -- you'll have to look up its number first using <tt>lpq</tt>.</li>
      <li>Having trouble printing from an application like xpdf or KWord? Try
      Saving your file as plain text of PostScript, then print it from the
      command line using lpr.</li>
  </ul>
