<span>MediaPrintableArea类是用于区分可打印区域和不可打印区域的打印属性。</span>
<p> <span>可打印区域在介质的总体尺寸内被指定为矩形。</span> </p>
<p> <span>由于打印机硬件限制，大多数打印机无法在介质的整个表面上进行打印。</span> <span>该类可用于查询假定的打印作业的可接受值，并请求在可打印区域的约束内的区域用于打印作业。</span> </p>
<p> <span>要查询可打印区域，客户端必须提供合适的上下文。</span> <span>至少没有指定使用的介质的尺寸，可以获得可印刷区域的有意义的值。</span> </p>
<p> <span>该属性没有以与纸张边缘的距离来描述，部分是为了强调该属性不是独立于特定媒体，而是必须在选择其他属性的上下文中进行描述。</span> <span>此外，客户端通常更方便地使用可打印区域。</span> </p>
<p> <span>硬件的最小边距不仅仅是打印机的属性，而是可能是介质尺寸，方向，介质类型和任何指定的功能的函数。</span> <span><code>PrintService</code>提供了在合适的上下文中查询属性的支持值的方法：参见<a href="../../../../javax/print/PrintService.html#getSupportedAttributeValues-java.lang.Class-javax.print.DocFlavor-javax.print.attribute.AttributeSet-"><code>PrintService.getSupportedAttributeValues()</code></a></span> </p>
<p> <span>矩形可打印区域由此定义：（x，y）原点位于纸张的左上角，而不管请求上下文中指定的方向如何。</span> <span>例如，纵向或横向A4纸的可打印区域的高度&gt;宽度。</span> </p>
<p> <span>可打印区域属性的值作为整数以微米（μm）为单位存储，其中1微米= 10 <sup>-6</sup>米= 1/1000毫米= 1/25400英寸。</span> <span>这允许将尺寸精确地表示为1/1000mm（=1μm）或1/100英寸（=254μm）的精度。</span> <span>如果分数英寸以两个负的幂表示，这允许尺寸精确地表示为1/8英寸（=3175μm）但不是1/16英寸的精度（因为1/16英寸不等于整数Âμm）。</span> </p>
<p> <span><b>IPP兼容性：</b> MediaPrintableArea不是IPP属性。</span> </p>
