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");
}

// 2:建立一个PDF 写入器与document对象关联通过书写器(Writer)可以将文档写入到磁盘中
