I am integrating an android app with Intermec PR3 printer. This is what what I done in order to implement the same.

  1. Download the drivers/ LinePrinter.jar from https://support.honeywellaidc.com/s/article/Where-to-download-Intermec-printing-SDK-for-Android
  2. Implement the code as per the samples provided. Add LinePrinter.jar to the classpath.

Install LinePrinterService app from honeywell onto the android prone.

Post that, I try to initialize LinePrinter with below code -

LinePrinter  lp = new LinePrinter(profiles.getAbsolutePath(), "PR3",
                "bt://68:0A:D2:4F:5X:K5", exSettings);

However, I get a weird exception -

W/System.err: com.intermec.print.lp.LinePrinterException: java.lang.Class<com.intermec.print.android.AndroidPrinter> is not accessible from java.lang.Class<com.intermec.print.Printer>
W/System.err:     at com.intermec.print.lp.LinePrinter.<init>(Unknown Source:18)
W/System.err:     at com.example.print_honeywell.FirstFragment.doPrint(FirstFragment.java:109)
W/System.err:     at com.example.print_honeywell.FirstFragment.access$000(FirstFragment.java:38)
W/System.err:     at com.example.print_honeywell.FirstFragment$1.onClick(FirstFragment.java:58)
W/System.err:     at android.view.View.performClick(View.java:7520)
W/System.err:     at com.google.android.material.button.MaterialButton.performClick(MaterialButton.java:1119)

Does anyone know what this exception mean? I am totally stuck on this.. Moreover somehow I cannot debug in android studio either, because driver sources are not available. Is it something to do with java version?

I'd the same problem and also downloaded the printer SDK from Where-to-download-Intermec-printing-SDK-for-Android link. But nothing works and the same error as you. I found another SDK jar file for the printer in the project I work on it.

So the solution that works for me:

  • I used the SDK I found in the project I work on it (I uploaded it to google drive for you)
  • install LinePrintService-release.apk (I uploaded it also into the same folder in google drive)

I hope that will work for you. Don't hesitate to ask.

  • I follow your solution but encounter LinePrinterException: Print Service is not available exception when trying to call lp = new LinePrinter( profiles.getAbsolutePath(), sPrinterID, sPrinterURI, exSettings); – user976385 Mar 02 '23 at 02:27
