我使用java打印多個html文檔時遇到問題。我需要的應用程序顯示ONE所有可打印文件的打印對話框(文件數可能很大)。首先,我試圖做到這一點使用非標準的Java方法:在java中批量打印
if (Desktop.isDesktopSupported()){
Desktop desktop = Desktop.getDesktop();
if (desktop.isSupported(Desktop.Action.PRINT))
{
try {
File html1 = new File("c://file1.html");
File html2 = new File("c://file2.html");
desktop.print(html1);
desktop.print(html2);
} catch (IOException e) {
e.printStackTrace();
}
}
}
但我看到每個打印的文件一個一個對話框,它不適合我。然後我試圖使用Java打印API,但事實證明,我的打印機不支持DocFlavor的HTML文件,我的支持列表DocFlavor的是這樣的:
image/gif; class="[B"
image/gif; class="java.io.InputStream"
image/gif; class="java.net.URL"
image/jpeg; class="[B"
image/jpeg; class="java.io.InputStream"
image/jpeg; class="java.net.URL"
image/png; class="[B"
image/png; class="java.io.InputStream"
image/png; class="java.net.URL"
application/x-java-jvm-local-objectref; class="java.awt.print.Pageable"
application/x-java-jvm-local-objectref; class="java.awt.print.Printable"
application/octet-stream; class="[B"
application/octet-stream; class="java.net.URL"
application/octet-stream; class="java.io.InputStream"
然後我試圖打印HTML文件作爲圖像(PNG,這是我在畫圖:)畫了),我的代碼:
PrintRequestAttributeSet pras =
new HashPrintRequestAttributeSet();
DocFlavor flavor = DocFlavor.INPUT_STREAM.PNG;
PrintRequestAttributeSet aset =
new HashPrintRequestAttributeSet();
aset.add(MediaSizeName.ISO_A4);
aset.add(new Copies(1));
aset.add(Sides.ONE_SIDED);
aset.add(Finishings.STAPLE);
PrintService printService[] =
PrintServiceLookup.lookupPrintServices(flavor, pras);
PrintService defaultService =
PrintServiceLookup.lookupDefaultPrintService();
PrintService service = ServiceUI.printDialog(null, 200, 200,
printService, defaultService, flavor, pras);
if (service != null) {
try {
FileInputStream fis = new FileInputStream("c://test//test.png");
DocAttributeSet das = new HashDocAttributeSet();
Doc doc1 = new SimpleDoc(fis, flavor, das);
FileInputStream fis2 = new FileInputStream("c://test//test2.png");
DocAttributeSet das2 = new HashDocAttributeSet();
Doc doc2 = new SimpleDoc(fis2, flavor, das2);
DocPrintJob job1 = service.createPrintJob();
DocPrintJob job2 = service.createPrintJob();
try {
job1.print(doc1, pras);
job2.print(doc2, pras);
} catch (PrintException e) {
e.printStackTrace();
}
} catch (FileNotFoundException e) {
e.printStackTrace();
}
}
它完美,而是convertation從HTML圖像並不簡單的問題。我嘗試使用swing組件,實現Printable接口並使用Cobra庫,但它要求在窗體上顯示文檔,這對我來說並不是必需的,因爲我需要在「無聲」模式下打印,而無需打開文檔。
任何想法?
在這個例子中,ASET是未使用的。它看起來像pdfbox 2.0.0將支持將PrintRequestAttributeSet傳遞給'silentPrint()'方法。 – Aaron 2014-06-19 23:24:44
