At my school, we quickly discovered that the admin password for all the networked printers was the name of the high school. All these HP laser jets had a function where you could upload custom translations for the status messages on the printer displays. So we downloaded the English string set (XML) and made some changes, “translating” for example, “Printer Ready” to read “Paper Jam”, “Replace Toner” and so on. As well as changing the admin password. The school actually RMA’d them back to HP thinking the paper jams were some sort of actual defect, as opposed to an altered status message, and eventually replaced them all with Brother printers. Oops lol
