android网络打印生成pdf

android通过局域网连接打印机不是很好实现，最近做了个通过android生成pdf上传到后台，后台调用pc驱动完成打印功能。

Desktop desktop;        if (Desktop.isDesktopSupported()) {            desktop = Desktop.getDesktop();            try {             <span style="color:#ff6666;">   desktop.print(new File("d:\\upload\\" + fileName));</span>                map.put("resultId", 1);                map.put("detail", "success print");            } catch (Exception e) {                // TODO: handle exception                e.printStackTrace();                map.put("resultId", 0);                map.put("detail", e.getMessage());            }        } else {            map.put("resultId", -1);            map.put("detail", "not Support print");        }

1:利用Itext插件生成pdf

public int dkzzszyfp() {// 1:建立Document对象实例Document document = new Document(PageSize.A4, 50, 50, 50, 50);FileOutputStream fos;try {fos = new FileOutputStream(new
