如何打印自定義紙張尺寸（檢查8「x 4」）？

我想從Java小程序打印自定義紙張大小。我已設置紙張尺寸，但它被忽略。如何打印自定義紙張尺寸（檢查8「x 4」）？

我也嘗試過使用本書的方法，因爲我已經看到了一些有關這有助於它的工作，但是當我用它時，它只是打印一個空白頁，似乎仍然是關於A4（我正在打印檢查這顯然要小得多（8「×4」））。

我想從JEditorPane打印HTML，如果這有什麼區別。

如果您有任何想法，我將非常感激，我正在用這個撕掉我的頭髮。

我還應該補充一點，就Java而言，我是一個非常初學者。

這是我到目前爲止有：

更新時間： 我現在拿到的頁面大小合適的，但似乎無法讓我加載到適應或與排隊HTML頁面頁面大小。

更新： 現在我只是不能讓小程序在瀏覽器中運行。它從eclipse起作用，而不是瀏覽器。我還需要從參數中傳遞URL。

這裏是我使用的HTML Applet標記和更新Java代碼：

打印設計爲以每英寸像素爲單位工作。基底印刷API使用的72

您需要將相應的測量轉換DPI ...

double paperWidth = 8 * 72d; 
double paperHeight = 4 * 72d; 
double margin = 1 * 72d;

更新，例如

g2d.setClip(0, 0, (int)pageFormat.getImageableWidth(), (int)pageFormat.getImageableHeight());病諫，危險的，一般，不除此之外，你已經使用了錯誤的寬度和高度值。可成像的參數考慮了邊距，但是您尚未翻譯圖形，這將更有可能切割底部，您必須打印的區域的左側部分...

我只是避免使用裁剪

感謝您的答覆，但這似乎並沒有改變任何東西。我很高興知道我是否可以接受我的紙張尺寸。 – Liam

@liam新增工作示例 – MadProgrammer

謝謝，這對我有很大的幫助，而且我越來越接近獲得我想要的東西。紙張大小是正確的，但我似乎無法得到我正在加載正確的大小或位置的HTML頁面。我更新了上面的代碼以顯示我現在擁有的內容。任何想法，我要去錯了嗎？ – Liam

如何打印自定義紙張尺寸（檢查8「x 4」）？
