KarmaKarma review for Shopify Order Printer

Thank you for sharing this feedback. The Shopify Order Printer app should be able to calculate the totals in the invoices. However, if you require assistance with customizing the template, then this is something that our Theme Support team can help you with. Simply visit the Shopify Help Center (https://shopify.link/vRnL) and let our advisors know that you'd like to create a customization request. Cheers. -Elias, Shopify Support
