JAVA连接打印机打印ADF文件

JAVA连接打印机打印ADF文件

首先要把需要打印的设备连接到当前的电脑上

        paper.setImageableArea(marginLeft, marginRight, width - (marginLeft + marginRight), height - (marginTop + marginBottom));

    }

 public static void main(String[] args) throws Exception {
        String pdfFile = "C:\\Users\\86155\\Desktop\\aa.pdf";//文件路径
        File file = new File(pdfFile);
        String printerName = "Brother DCP-7180DN";//打印机名包含字串
        PDFprint(file,printerName,1,false);
    }

目前只是本地可以，如果部署到服务器就找不到打印机。有更好的解决方案可以讨论下
