Script Description

The pjl-ready-message.nse script retrieves or sets the ready message on printers that support the Printer Job Language. This includes most PostScript printers that listen on port 9100. Without an argument, displays the current ready message. With the pjl_ready_message script argument, displays the old ready message and changes it to the message given.
