Penetration Testing: Dumping Data From Printers

[ahgaber_rehan () yahoo com]

I wonder if there is a tool that can enable a person to dump the print jobs , or data sent to Network Printers?

Another question 

what would be the greatest risk if network admin leave Network printers without password protected.

i can telnet to the printer, gain access to the configuration file, which can enable me to stop the printer function, 
changing network configuration. 
But istill see the greatest risk is getting the printed data. any one can advice on this ??
