我遵循Zebra Android Link_OS SDK示例代码,通过蓝牙在ZQ510上打印测试标签,但不会以ZPL格式打印。Zebra打印机不会打印ZPL格式
这里是我运行打印标签的代码:
private void sendZplOverBluetooth(final String theBtMacAddress) {
new Thread(new Runnable() {
public void run() {
try {
// Instantiate connection for given Bluetooth® MAC Address.
Connection thePrinterConn = new BluetoothConnection(theBtMacAddress);
// Initialize
Looper.prepare();
// Open the connection - physical connection is established here.
thePrinterConn.open();
// This example prints "This is a ZPL test." near the top of the label.
String zplData = "^XA^FO20,20^A0N,25,25^FDThis is a ZPL test.^FS^XZ";
// Send the data to printer as a byte array.
thePrinterConn.write(zplData.getBytes());
// Make sure the data got to the printer before closing the connection
Thread.sleep(500);
// Close the connection to release resources.
thePrinterConn.close();
Looper.myLooper().quit();
} catch (Exception e) {
// Handle communications error here.
e.printStackTrace();
}
}
}).start();
}
这里是打印的结果。 (我跑了两次,这就是为什么有两个测试打印)。
然后我读到它是如何处于不同的模式,因为由于某种原因,斑马无法检测到他们自己的专有语言。所以我试图获取设置并查看Android应用。再次使用给定链路-OS SDK示例代码:
private static void displaySettings(Connection c) throws ConnectionException, ZebraPrinterLanguageUnknownException, SettingsException, ZebraIllegalArgumentException {
ZebraPrinter genericPrinter = ZebraPrinterFactory.getInstance(c);
ZebraPrinterLinkOs linkOsPrinter = ZebraPrinterFactory.createLinkOsPrinter(genericPrinter);
if (linkOsPrinter != null) {
System.out.println("Available Settings for myDevice");
Set<String> availableSettings = linkOsPrinter.getAvailableSettings();
for (String setting : availableSettings) {
System.out.println(setting + ": Range = (" + linkOsPrinter.getSettingRange(setting) + ")");
}
System.out.println("\nCurrent Setting Values for myDevice");
Map<String, String> allSettingValues = linkOsPrinter.getAllSettingValues();
for (String settingName : allSettingValues.keySet()) {
System.out.println(settingName + ":" + allSettingValues.get(settingName));
}
String darknessSettingId = "print.tone";
String newDarknessValue = "10.0";
if (availableSettings.contains(darknessSettingId) &&
linkOsPrinter.isSettingValid(darknessSettingId, newDarknessValue) &&
linkOsPrinter.isSettingReadOnly(darknessSettingId) == false) {
linkOsPrinter.setSetting(darknessSettingId, newDarknessValue);
}
System.out.println("\nNew " + darknessSettingId + " Value = " + linkOsPrinter.getSettingValue(darknessSettingId));
}
}
这一次,我得到一个SettingsException
与Operation cannot be performed on raw channel with a printer set to line print mode
我如何能够使用Mac和正确地开发Android打印ZPL文字说明?我阅读了关于使用一些Zebra Utility应用程序来改变模式,但它仅适用于Windows,并且他们的Android应用程序不起作用。无论如何,如果有人在不正确的模式下使用打印机的应用程序,他们将不得不经历所有这些不必要的设置,这对任何人都不是直观的。
感谢您的帮助和欣赏任何反馈。
我建议您添加一个较小的问题图片,我认为这个帖子对于帖子太大了。 – Dayan
