    <p>You can't prevent the user from printing, but you can hide everything when the user prints the document by using simple CSS:</p> <pre><code>&lt;style type="text/css" media="print"&gt; * { display: none; } &lt;/style&gt; </code></pre> <p><a href="http://jsfiddle.net/qaapD/11/" rel="nofollow noreferrer">Updated fiddle</a>.</p> <p>If you would like to show the visitor a custom message when he/she try to print rather then just a blank page, it's possible with client side code but first wrap all your existing contents like this:</p> <pre><code>&lt;div id="AllContent"&gt; &lt;!-- all content here --&gt; &lt;/div&gt; </code></pre> <p>And add such a container with the custom message:</p> <pre><code>&lt;div class="PrintMessage"&gt;You are not authorized to print this document&lt;/div&gt; </code></pre> <p>Now get rid of the <code>&lt;style type="text/css" media="print"&gt;</code> block and the code would be:</p> <pre><code>if ('matchMedia' in window) { // Chrome, Firefox, and IE 10 support mediaMatch listeners window.matchMedia('print').addListener(function(media) { if (media.matches) { beforePrint(); } else { // Fires immediately, so wait for the first mouse movement $(document).one('mouseover', afterPrint); } }); } else { // IE and Firefox fire before/after events $(window).on('beforeprint', beforePrint); $(window).on('afterprint', afterPrint); } function beforePrint() { $("#AllContent").hide(); $(".PrintMessage").show(); } function afterPrint() { $(".PrintMessage").hide(); $("#AllContent").show(); } </code></pre> <p>Code is adopted from <a href="https://stackoverflow.com/a/15662720/447356">this excellent answer</a>.</p> <p><a href="http://jsfiddle.net/qaapD/13/" rel="nofollow noreferrer">Updated fiddle</a>.

    3. COif you absolutely had to disable Ctrl+p (which, of course, everyone knows you should never do) it would probably be nice to mention that you'd done it with an inline message / popup dialog when Ctrl+p is pressed.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
