There is a way to distribute the risk such that any single print-shop gains no benefit from copying your files: Visual Cryptography.
But it is esoteric and it is hard-core - versus simply buying your own printer or eBook reader.
To print PDFs at untrusted print-shops with visual cryptography, you use special software to split each page into two parts - each which you print on a transparency (a/k/a lecture slide) at entirely separate print-shops*. You can then view the document by leafing through glued transparencies.
The resolution depends on a variety factors such as the intelligence of the separation algorithm but will be fairly low (1980's monitor resolution).
* Preferably while wearing a Groucho Marx disguise and providing fake ID if your totalitarian state requires it.
