You can do research on the type printers that law in forcemeat officers have in their cars. I'm a reserve officer and in our cars we have a printer for printing tickets when wrote in the car on the spot. Cuts down paper work drastically. With that said. The police cars run more than they are stopped so their is no real issues with anything happening to the ink or internals. Also these units are bolted down. I've not paid much attention to how I just use them. Here in Alabama the weather isn't that bad either though.
