Shipping method missing on packing slip

Hello people smarter than me,

Bought the PDF invoices and packing slips a while ago though keep getting complaints from our logistics department that the packing slip doesn’t show whether it needs to be shipped or will be picked up. I would prefer it to state the shipping method underneath either the invoice or shipping details.

I must admit I am new to this forum so if I missed any information or procedures please excuse me and let me know so I’ll add it/ refrain from doing so.

* Have been looking through the FAQ and this forum but couldn’t find anything on the topic besides someone wanting to hide the shipping method which made me wonder how he got it in the first place. The ticket we opened resulted in one line to be added to the php file of the packing slip that unfortunately resulted in a fatal error so even suggestions resulting in fatal errors I am happy to try out at this point.
