The Secret Life of Printers

Today I had to 'regionalize' our printer. An hp rep walked me through the steps online, over a chat window. I discovered many functions that the regular buttons that we use for regular purposes perform when they are pressed in different combinations. He even made me double-click an HP logo while I held the ctrl key down to bring up a completely unique window where I entered secret numeric combinations that he gave me - a window that I had never seen before in my entire life. I just realized that there is a whole another world of key combinations and single- and double-clicks out there (or rather, in there in our computers) that serve purposes we don't even become aware of unless we bring a printer from Turkey and buy cartridges for it in the US. It's the secret life of printers and their secret affairs with computers.
