buffer builder error

[shaniqwa]

getting these errors:

ERROR in node_modules/escpos-xml/lib/buffer-builder.ts(9,19): error TS2554: Expected 2 arguments, but got 0.
node_modules/escpos-xml/lib/buffer-builder.ts(150,5): error TS2322: Type 'Buffer' is not assignable to type 'number[]'.
  Property 'push' is missing in type 'Buffer'.

I have fixed it by changing the return to return Array.prototype.slice.call(this.buffer.flush(), 0); in buffer-builder.ts line 150

I also have this issue but slightly changed

[app-scripts] [20:23:25]  typescript: node_modules/escpos-xml/lib/buffer-builder.ts, line: 9
[app-scripts]             Expected 2 arguments, but got 0.
[app-scripts]        L8:    constructor(private defaultSettings: boolean = true) {
[app-scripts]        L9:      this.buffer = new MutableBuffer();

It seems like it doesn't like that. I'm not using that feature and I used //@ts-ignore but this should definitely be something to look at and fix.
