android - 如何在 MobiWire MobiPrint 3 (Android) 上打印

Question

我有带集成热敏打印机的 MobiWire MobiPrint 3 设备 (Android 4.2.2)，我正在尝试在 Android Studio 中制作一个简单的应用程序以在该打印机上打印一些东西。

有人有此设备的 API 文档吗？尝试联系 Mobiwire 但没有帮助..

在 Android 4.2.2、ESC/POS 上打印的最佳方式是什么？我必须只打印文本(发票)。

谢谢。

试试这个:

AndroidManifest.xml

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

在Activity或Fragment中调用此函数

fun print() {
    if (printer.printerStatus == Printer.PRINTER_STATUS_OK) {
        val printer = Printer.getInstance()
        printer.printText("Some Text")
        printer.printText("Another Text")
        printer.printText("Add as many Texts")
        // And finally add this line
        printer.printEndLine()
    } else {
        println("_print::(printerStatus:${status(printer.printerStatus)})")
    }
}

private fun status(s: Int) = when (s) {
    Printer.PRINTER_STATUS_OK -> "Printer Ok"
    Printer.PRINTER_ERROR -> "Error printing, try again"
    Printer.PRINTER_NO_PAPER -> "Not paper, insert paper and try again"
    Printer.PRINTER_STATUS_GET_FAILED -> "Printer not working correctly"
    Printer.PRINTER_STATUS_OVER_HEAT -> "Printer overheated, wait for it to cool"
    else -> "No printer found on this device"
}
