Description
I have tried the example you provided but still cannot print images
I have also read on issues on escpos-php
he said "Graphics are supported on the TM U220. The trick is to use single-density graphics only, and a much older print command." and he gives an example but it's a different library and different programming language, how do I do that with node-escpos?
