I am not proficient in using liquid. I have managed to create a custom packing slip that prints with a 4x6 thermal printer and figured out how to add the product line cost, shipping method, shipping cost and order total cost to the packing slip.
I would also like to add a sales tax line item but I cannot figure out how to do that. The order total cost actually includes the sales tax collected, but I cannot find a way to display the sales tax.
Thanks in advance for any help!
