蓝牙和WIFI打印为Android [英] Bluetooth and WIFI Printing for Android
问题描述
我们需要一个便携式打印机（手持式，这一点很重要），可以通过蓝牙或WiFi连接到Android手机。
We would need a portable printer (handheld, it is important) that can connect to android phone via bluetooth or wifi.
- 在没有标准的打印SDK可用于Android这个时间
- 有一个非官方SDK称为 iPrint的SDK 。你们中尝试过通过WiFi或者蓝牙？它的工作原理？
- 的PrinterShare 还声称自己是的 programmaticly提供。这将是确定对我来说，每部手机缴纳一次费用$ 5的。它有很多支持的格式。您是否尝试过与任何手持设备？我问他们有关支持的蓝牙打印机列表中（因为它有一个菜单项搜索BT打印机），但他们并没有回答。
- No standard printing SDK available for Android this time
- There is a non official SDK called iPrint SDK. Have any of you tried it through wifi or bluetooth? Does it work?
- Printershare also claims to be programmaticly available. It would be ok for me to pay the one time fee $5 for it per phone. It has a lot of supported formats. Have you tried it with any handheld device? I asked them about the list of supported bluetooth printers (since it has a menu item "search for BT printer"), but they did not answered.
- 如何从你的android应用程序打印？
- 请你用什么样的打印机
- 是否计划在标准Android SDK，包括印刷？什么是路线图？它是目前可用的测试版还是什么？
- 如果我们以某种方式（我不这么认为）建立自己的解决方案通过蓝牙打印，你可以推荐标准和协议检查和学习？
推荐答案
与
Starting with Android 4.4 you can print documents from a device to a hardware printer via wifi.
Android应用程序现在可以打印任何类型的通过Wi-Fi或云托管服务，如谷歌云打印的内容。在打印功能的应用程序，用户可以发现可用的打印机，更改纸张尺寸，选择特定的页面打印，和打印几乎任何类型的文档，图片或文件。
Android apps can now print any type of content over Wi-Fi or cloud-hosted services such as Google Cloud Print. In print-enabled apps, users can discover available printers, change paper sizes, choose specific pages to print, and print almost any kind of document, image, or file.
如何开始打印过程中一个简单的例子：
A brief example of how to start the printing process:
private void doPrint() {
PrintManager printManager = (PrintManager) getActivity().getSystemService(Context.PRINT_SERVICE);
printManager.print("My document", new CustomPrintDocumentAdapter(getActivity()), null);
}
