1.帮助文档调默认打印机
// 定义报表运行环境,才能执行报表
String envPath = onLinePoint;
FRContext.setCurrentEnv(new LocalEnv(envPath));
try {
TemplateWorkBook workbook = TemplateWorkBookIO.readTemplateWorkBook(FRContext.getCurrentEnv(), fileName+".cpt");
// 参数传值
Parameter parameters = workbook.getParameters();
HashMap paraMap = new HashMap();
paraMap.put(parameters.getName(), packCode);
// java中调用报表打印方法
boolean a = PrintUtils.printWorkBook(fileName+".cpt", paraMap, false);
if (a == false) {
System.out.println("失败啦！返回" + a);
this.returnData.toSuccess("打印封箱单失败！");
} else {
this.returnData.toSuccess("打印封箱单成功！");
System.out.println("成功！返回" + a);
}
} catch (Exception e) {
e.printStackTrace();
}
2.需求调用指定打印机
public static void print(PrintableSet printableset, boolean flag, String s)
throws PrinterException
{
print(printableset, flag, s, 0);
}
public static void print(PrintableSet printableset, boolean flag, String s, int i)
throws PrinterException
{
PrintService printservice = null;
if(s != null)
{
PrintService aprintservice = PrintServiceLookup.lookupPrintServices(javax.print.DocFlavor.INPUT_STREAM.AUTOSENSE, null);
int j = 0;
do
{
if(j >= aprintservice.length)
break;
if(s.equals(aprintservice.getName()))
{
printservice = aprintservice;
break;
}
j++;
} while(true);
}
if(printservice == null)
printservice = PrintServiceLookup.lookupDefaultPrintService();
PrinterJob printerjob = PrinterJob.getPrinterJob();
if(printservice != null)
printerjob.setPrintService(printservice);
if(printableset.size() == 0)
{
return;
} else
{
getPageablePrintBook(printerjob, printableset, printservice, flag, i);
printerjob.print();
return;
}
}
3.问：上面方法是否能满足需求；
参数中PrintableSet如何使用、String s 是否打印机名称；
具体实现步骤。
