Worked at a sales department in 2010, my office (or closet) was in front of the main A3 printer. It was running dusk till dawn. Most of the employee despise computers (partially for good reasons: bad IT contracts and not tailored tools and devices =&gt; rageprint).<p>Most of the prints had a lifespan of 1 hours before being thrown out. Mostly scratchpad for too large spreadsheets.
