JSPrintManager implementation for Angular 8

This is the Angular 8 adaptation of the sample of JSPrintManager you can find here: https://www.neodynamic.com/articles/How-to-print-raw-ESC-POS-commands-from-Javascript/

Example can be found at: ./index.html using ./JSPrintManager

DISCLAIMER: I Am Not An Angular Expert, So I Think This Implementation Is The Simplest Way To Use The Documentation Example In An Angular Context. I used the default template provided by running ng new
