How to use the webpack...

Hi everyone, I'm trying to use a thermal printer but I keep on getting the below error.

The application can connect to the bluetooth printer.
I've also installed other applications from the playstore on my phone just to see if I can print on the thermal printer and they all can print however, when I use this lib, my application cannot print.

I have created a folder under *project/src/app/workers and also created files(enable-bluetooth.js, connect-printer.js)

• Any ideas?

I have the 1.0.1.1801PRO.jar for hprt. The jar is missing the header files though that this version has. Been trying to work on an updated version for this plugin but not having much luck. How did you generate the header files from the given jar?

Hi @krushkamx

First of all, thank you for the great plugin, it has helped us immensely on the current project.

I am trying to connect to multiple devices but iterating through the search printer results I realise that the results are basically all devices paired in the past, and when I connect with the results using HPRT.connect(result) it basically allows me to connect even when the device is switched off - that is to say, even for the devices that are switched off it goes in the then() instead of catch(). Can you please shed some light on this, is this expected behaviour.

Hi!! im trying to create an app with svelte native, to use on sunmi V2 pro android device, but im getting this error when install this script.

Error: Cannot find module rxjs/Observable File: (file:///data/data/org.nativescript.posprint/files/app/vendor.js:53249:89)
I also had the following error: Error: Cannot find module 'utils/utils' which I think I have solved with

webpack.chainWebpack((config) => {
config.resolve.alias.set(
"@nativescript/core/utils/utils",
"@nativescript/core/utils"
);
config.resolve.alias.set("utils/utils", "@nativescript/core/utils");
config.resolve.alias.set(
"tns-core-modules/utils/utils",
"@nativescript/core/utils"
);
config.resolve.alias.set("tns-core-modules", "@nativescript/core");
});

Any idea how I can solve these problems?
