I wonder if the other end is a person who'd rather have stacks of physical objects as their task list: read what the issue is, write down how to fix it, hand it over to someone who'll run and fix the problem, and give the replacement object and the paper to a delivery driver, job done.
They could digitize it, but this person would just be staring at the screen the whole day, and then has to click print and people have to wait, etc. Maybe they could amazonize it and have e-ink QR codes and scanners and robots that scan a code and fetch the next job over WiFi or 5G, but, hey, the whole idea's been discussed in the C-level for 5 years now! Especially if there's hundreds of such depots.
Although obviously the input side, at your supermarket, could be digitalized, and they could outsource a software that basically prints everything, replacing this person's fax machine, but hey, that idea's going to take 3 years to materialize, and they'll have to put such a computer with the software on each supermarket and it's been there since 2002, so...
You lose your hair thinking about inefficiencies...
