Printing:

• To print, call printerDetails.print(context, template, printingOptions, dontPrintTrailerFlag)

  • context is the UI Context object.
  • template is the Template object (reference the Open Templates page).
  • printingOptions is the PrintOptions object we initialize (reference below).
  • dontPrintTrailerFlag is a Boolean that represents if we want a trailer on our label.

• The SDKs PrintingOptions is used to set CutOptions and the number of copies to print.

  • PrintingOptions printingOptions = new PrintingOptions(); printingOptions.setCutOption(CutOption.EndOfJob); printingOptions.setNumberOfCopies(1);

• Similar to connecting, it is recommended to call the .print() method inside another thread.

  • A progress bar can be used similar to when we connected to the printer.
  • All together, a UI's print function may look like:

public void printTemplate(Template template) {
    PrintingOptions printingOptions = new PrintingOptions();
    printingOptions.setCutOption(CutOption.EndOfJob);
    printingOptions.setNumberOfCopies(1);
    printingOptions.setIsCollated(true);
    Runnable r = () -> {
        runOnUiThread(()->progressBar.setVisibility(View.VISIBLE));
        printerDetails.print(context, template, printingOptions, null);
        runOnUiThread(()->progressBar.setVisibility(View.INVISIBLE));
    };
    Thread printThread = new Thread(r);
    printThread.start();
}

• Alternatively, if the desire is to simply print an image instead of a Brady Workstation template, you may use the print method shown below.

public void print(Bitmap bitmap) {
        PrintingOptions printingOptions = new PrintingOptions();
        printingOptions.setCutOption(CutOption.EndOfJob);
        printingOptions.setNumberOfCopies(1);
        Runnable r = () -> {
            runOnUiThread(()->progressBar.setVisibility(View.VISIBLE));
            printerDetails.print(context, bitmap, printingOptions, false);
            runOnUiThread(()->progressBar.setVisibility(View.INVISIBLE));
        };
        Thread printThread = new Thread(r);
        printThread.start();
    }

• Use extensions such as PNGs, JPGs, JPEGs, WEBPs, or SVGs can be converted into a Bitmap. For example, "selectedFileName" was a file named "bradylogo.png" that the user selected:

String selectedFileName = templatesSpinner.getSelectedItem().toString();
InputStream iStream = getResources().openRawResource(getResources().getIdentifier(selectedFileName.split("[.]")[0], "raw", getPackageName()));
bitmap = BitmapFactory.decodeStream(iStream);
