Custom printing in wordpress. Just change the size of it.

Job ID: 32661865

Budget: $10 – $30 USD

Hello I have a website that needs to print labels and receipts but the plugins I'm using doesn't offer any customization options so I only need to customize the size of the receipt for an special printer.
First one is Wepos plugin
https://wordpress.org/plugins/wepos/
According to they support I can customize my receipt using wp_enqueue_style function in wordpress. I need to be able to customize what is show in the receipt and of course the size as well. Source code is here:
https://github.com/weDevsOfficial/wepos/blob/develop/assets/src/utils/store/modules/Order.module.js
Support says the plugin is made using v3.vuejs.org framework and I'm not sure where to look or where to add this wp_enqueue_style function.

Prove you are reading this contact me with code word "lucino". Second plugin is:
https://wordpress.org/plugins/product-barcode-generator/
Not support at all but source code is in wordpress directory so you can take a look:
https://plugins.trac.wordpress.org/browser/product-barcode-generator?order=name

As I said I only need to change the size of the receipt so I can print it on my printer the specific size.
I'll also need you to tell me where the changes to the source code has been made.
If you think you can do it please give me a clue how you would do it so I can be sure you're the one.
Thanks in advance.
