Very nice Sander!! I knew Ruby could have multiple returns, so it's great
to know that for Angular as well!

Hi Harry,
something like:
async findPrintAndScales() {
try {
await qz.websocket.connect();
const printers = await qz.printers.find();
const devices = await qz.hid.listDevices(false);
await qz.websocket.disconnect();
return [printers, devices];
} catch (e) {
console.log('uhOh', e);
}
}
should do t
That worked like a charm Sander!!
Here's my code now:
qz.websocket.connect().then(function() {
return qz.printers.find();
}).then(printers => {
console.log(printers);
this.chosePrinter(printers);
return qz.hid.listDevices(false);
}).
Hi Harry,
I took a closer look to your screenshot. (BTW, pasting snippets as code
makes it easier to spot issues and help you)
It is a 'this' problem indeed.
In JS, each function had it's own 'this' That means the 'this' in the
function, is not your class. Hence the error.
Replace the function w
Hello Tito!
That function is in the same component class. It looks like this:
choseScale(devices){
console.log("ChoseScaleData = " + devices);
}
At runtime, I get this in the browser console:
qztray.component.js:49 TypeError: Cannot read property 'choseScale' of
undefined
Where is choseScale? I dont see it
