<span>PrinterResolution类是一个打印属性类，它指定打印机支持的准确分辨率或用于打印作业。</span>
|
||
<span>该属性假设打印机具有一小组设备分辨率，在这些设备分辨率下可以进行操作，而不是连续体。</span>
|
||
<p> <span>PrinterResolution以多种方式使用：</span> </p>
|
||
<ol type="1">
|
||
<li> <span>当客户端搜索正确地寻找支持客户端所需分辨率的打印机（不再更多，不少于）时，客户端会指定一个PrinterResolution类的实例，指示客户端想要的确切解决方案。</span> <span>只有支持该精确分辨率的打印机才能匹配搜索。</span> <p></p></li>
|
||
<li> <span>当客户端需要使用客户端所需的分辨率（不再更多，不少于）打印作业时，客户端将PrinterResolution类的实例指定为打印作业的属性。</span> <span>如果打印作业不支持精确的分辨率，并且将Fidelity设置为true，则此操作将失败。</span> </li>
|
||
</ol>
|
||
<span>如果客户端想要找到一个支持大于某一最小要求的分辨率的打印机，则可能需要从查找请求中排除该属性，并直接查询支持的分辨率集，并指定最接近客户端要求。</span>
|
||
<span>在某些情况下，这可以通过指定经常控制分辨率的PrintQuality属性来更简单地实现。</span>
|
||
<p></p>
|
||
<p> <span><b>IPP兼容性：</b>可以通过调用PrinterResolution对象上的方法来获取构建IPP <code>"printer-resolution"</code>属性所需的信息。</span> <span>由<code>getName()</code>返回的类别名称提供IPP属性名称。</span> </p>
