View source for Information disclosure

Apart from print jobs, printers may contain further potentially sensitive information like passwords – not only for the device itself but sometimes even to the surrounding network environment.

''Currently, the following information disclosure categories are discussed in this wiki:''

* [[Memory access]] – Dumping the printer's NVRAM using proprietary PJL commands
* [[File system access]] – Performing file system operations using PostScript and PJL
* [[Credential disclosure]] – Obtaining PJL and PostScript passwords by brute-force attacks
