Barcode on Shopify's default packing slip

Hi,

I would like to show a barcode of a order number, and a barcode of a ean number on the Shopify Packing Slip Template, so that my work can be done with higher efficiency and less mistakes.

Please recommend solutions using Shopify’s own markup language.

I have already searched for solutions from the Shopify Community, but none of them are working properly.

For example, this post and this post.

No matter how complicated, I will try to do it.

And please use this feature as default, @Shopify_77 . It is the year 2022, computers should be able to read papers already.

Sincerely,

Bahetiya
