Quote from OA

"TYCO Print is a printing service where professors can upload course files for TYCO to print out for students as they order. Shorter packets can cost around $20, while longer packets can cost upwards of $150 when ordered with the cheapest binding option."

And later in OA it states that the cost to a student is $0.12 per double sided sheet of printing.

In all of my teaching career here in the UK, the provision of handouts has been a central cost. Latterly I'd send a pdf file with instructions and the resulting 200+ packs of 180 sides would be delivered on a trolley printed, stapled with covers. The cost was rounding error compared to the cost of providing an hour of teaching in a classroom (wage costs, support staff costs, building costs including amortisation &c).

How is this happening?
