I've only seen pen and paper at work in connection with things where real paper signed with actual pens was required by law in such unambiguous terms that nobody felt like taking the risk of PDFs or a boolean database column. So, less than once per year. I've never printed anything for work and I'm not really sure how I would correctly print something. I think there is one printer in my branch office, somewhere?

I haven't seen any production process in automotive involve hand-written paper and I doubt it exists. Automotive supply chains have always been under massive cost pressure and therefore were always at the forefront of the most deeply digitized and automated supply chains.
