本文介绍了一种使用Java打印Word和Excel文档的方法，通过设置打印机名称并指定打印范围来实现精确打印。对于PowerPoint，则建议将其转换为PDF后再进行打印。

最近做项目需要打印office，搞了好久，现在分享下。打印word和excel是可以根据参数设置打印机的，但是ppt的ActivePrinter属性是只读的，不能设置打印机，看了ppt只能转换为PDF再打印了

private static void printWord(PrintService printService, byte[] content, String type, PageRanges pageRanges){

        //得到文件路径
        String filePath = getPrintUtils().writeTemporaryFile(content, type);
        ActiveXComponent app = null;    //word运行程序对象
        Dispatch doc = null;    //word文档
        try{
            ComThread.InitSTA();
            //创建ActiveX部件对象
            app = new ActiveXComponent("Word.Application");
            //设置打印机名称
            app.setProperty("ActivePrinter", new Variant(printService.getName()));
            Dispatch.put(app, "Visible", new Variant(false));
            //打开word文档
            Dispatch docs = app.getProperty("Documents").toDispatch();
            doc = Dispatch.invoke(docs, "Open", Dispatch.Method, new Object[]{filePath, new Variant(false), new Variant(true), new Variant(false)},
                    new int[1]).toDispatch();
            //开始打印
            Object[] object = new Object[2];
            object[0] = Variant.VT_MISSING;
            object[1] = Variant.VT_MISSING;
            if(pageRanges != null) {
                object[0] = new Integer(pageRanges.getMembers()[0][0]);
                object[1] = new Integer(pageRanges.getMembers()[0][1]);

}

//object对象具体参数可参考MSDN上word的Document方法设置参数

            Dispatch.callN(doc, "PrintOut", object);
        }catch (Exception e){
            e.printStackTrace();
            return;
        }finally {
            if(doc != null){
                Dispatch.call(doc, "Close", false);
            }
            if(app != null){
                app.invoke("Quit", 0);
            }
            ComThread.Release();
            //删除临时文件
            File file = new File(filePath);
            file.delete();
        }

}

private static void printExcel(PrintService printService, byte[] content, String type, PageRanges pageRanges){
        String filePath = getPrintUtils().writeTemporaryFile(content, type);
        ActiveXComponent app = null;    //word运行程序对象
        Dispatch excel = null;    //Excel文档
        try {
            ComThread.InitSTA();
            app = new ActiveXComponent("Excel.Application");
            // 打开文档
            Dispatch.put(app, "Visible", new Variant(false));
            Dispatch workbooks = app.getProperty("Workbooks").toDispatch();
            excel = Dispatch.call(workbooks, "Open", filePath).toDispatch();
            //开始打印
            Object[] object = new Object[8];
            object[0] = Variant.VT_MISSING;
            object[1] = Variant.VT_MISSING;
            if(pageRanges != null){
                object[0] = new Integer(pageRanges.getMembers()[0][0]);
                object[1] = new Integer(pageRanges.getMembers()[0][1]);
            }
            object[2] = Variant.VT_MISSING;
            object[3] = new Boolean(false);
            object[4] = printService.getName();
            object[5] = new Boolean(false);
            object[6] = Variant.VT_MISSING;
            object[7] = Variant.VT_MISSING;
            //object对象具体参数可参考MSDN上excel的Workbook方法设置参数
            Dispatch.callN(excel,"PrintOut",object);
        }catch (Exception e){
            e.printStackTrace();
        }finally {
            if(excel != null){
                Dispatch.call(excel, "Close", false);
            }
            if(app != null){
                app.invoke("Quit", new Variant[] {});
            }
            ComThread.Release();
            //删除临时文件
            File file = new File(filePath);
            file.delete();
        }
