Java - 如何將PDF打印到特定的打印機？

Question

我在Windows 8.1中有5個打印機，而PDF文件不在本地系統中生成的PHP服務器中。

問題。我如何從服務器獲取PDF文件並打印到特定打印機？

我與Apache PDFBox的努力2.0.0

      job.setPageable(new PDFPageable(pdf));

     } catch (Exception e) {

     } else { 
     System.out.println("[FAIL] - download fail");

    } catch (Exception ae) { 
     System.out.println("[FAIL]" + ae); 
    } 


    } 
}

這給你回可用打印機的列表：

PrintService[] services = PrinterJob.lookupPrintServices(); 

你可以循環這個ar並按名稱選擇打印機（服務[i] .getName（））
