Infrared printing tale
About 15 years ago the company I worked for bought a HP Laserjet. It came with an Infrared port that was on a lead that plugged into a serial port (it looked like a small mouse). The idea being that a user could maneuver the IR port to line up with their laptop to send a print job (not that IR printing ever worked!).
Anyhow, I was setting the printer up whilst a colleague was configuring the network queue (Novel as I recall). While I was plugging it in and filling it with paper a Senior Design Engineer saw me tinkering with the IR "mouse" and asked what it was. With tongue firmly in cheek, I said it was a voice-recognition device for the printer. She didn't believe me until I said "print test page" whilst holding the IR port up to my mouth. She didn't know my colleague had already queued up said test page on the Novel queue so, sure enough, out popped a test page once the printer had warmed up.
She was gobsmacked.
Absolute true story.
