我正在尝试打印pdf文档的多个副本.在谷歌搜索后,我发现我必须将一个副本放在PrintRequestAttributeSet中.但在这样做之后,只打印了1份而不是我提供的数量.

在调试期间,我可以看到打印对象将其副本变量从0更改为2,因此我假设我正确地执行了所有操作.我也一直在玩collat​​ion和multipledocumenthandling变量,但最终结果保持不变.

有谁知道我怎么能打印出正确数量的副本？

我的代码:

import java.io.BufferedInputStream;
import java.io.FileInputStream;
import java.io.InputStream;

import javax.print.Doc;
import javax.print.DocFlavor;
import javax.print.DocPrintJob;
import javax.print.PrintService;
import javax.print.PrintServiceLookup;
import javax.print.SimpleDoc;
import javax.print.attribute.HashPrintRequestAttributeSet;
import javax.print.attribute.PrintRequestAttributeSet;
import javax.print.attribute.standard.Copies;
import javax.print.attribute.standard.MultipleDocumentHandling;
import javax.print.attribute.standard.SheetCollate;

public class PrintTest {

    public static void main(String[] args) throws Exception {
        // TODO Auto-generated method stub
        InputStream is = new BufferedInputStream(
                new FileInputStream(
                        "<Insert pdf file here>"));

        DocFlavor flavor = DocFlavor.INPUT_STREAM.AUTOSENSE;

        Copies copies = new Copies(2);

        SheetCollate collate = SheetCollate.COLLATED;

        MultipleDocumentHandling handling = MultipleDocumentHandling.SEPARATE_DOCUMENTS_COLLATED_COPIES;

        PrintRequestAttributeSet pras = …

我正在使用JEE 7构建一个REST服务并在WildFLy 8上部署它.一切似乎都应该正常工作,除非PathParam它不是.

我的代码如下:
