How to send my custom invoice to shopify POS to be printed

[PedroSebastiaan]

Hi everybody, I'm the developer of a private plugin that we install in some Shopify stores. In our integration, I have a plugin that generates invoices when orders are paid, using Shopify's orders/paid webhook (which has been working fine). However, here's the issue: some of our clients use Shopify POS. I generate invoices for these sales and send them to customers via email, but the seller wants to automatically print that invoice when the sale is confirmed in the POS app. I've searched through various forums and pages but haven't found useful information. Has anyone encountered this problem or have any ideas on what I can do?
