PRETty

PRETty is useful when a large number of printers are present on a network. Instead of scanning, logging, and manually running PRET against each individual printer, it will automatically discover and run chosen PRET payloads against all printers on the target network.

Additionally, it can be used to automate command/payload delivery to any given list of printers.
