This is literally my business!
I work for an automaker and part of my group's responsibility is authoring and publishing service manuals (in additional to a whole bunch of other things).
To answer the question: Yes, we do still publish printed material. We don't print a lot, but there are still customers who want printed material and are willing to pay for it.
The majority of our delivery is electronic. This is available to purchase both on a subscription basis or as a USB drive for a single model year vehicle.
The printed stuff is typically purchased by upfitters and truck rental companies, so trucks and vans are most popular. There are also some customers of "prestige" models that like to have a print manual as a collectible for their vehicle.

Yeah, pretty much. Last I remember hearing it discussed, a print manual for a full size truck is 9 volumes.
