: New firmware can expand the range of configurable settings, such as paper size options or administrative controls.
The upgrade procedure required either Web JetAdmin or a command-line TFTP client with specific parameters. A failed upgrade was often catastrophic, requiring a return-to-factory via a physical jumper on the board. This fragility highlights a core philosophy of the era: firmware was a "once or twice in the device's life" event, not a continuous delivery pipeline. HP released updates primarily to fix critical bugs (e.g., memory leaks when processing PJL commands) or to patch the occasional, highly publicized Telnet vulnerability—never for feature additions.
