1-18 IPDS
1-18-1 Function Overview
Intelligent Printer Data Stream (IPDS) is a structured field data stream. It allows both data and
commands to be streamed to the printer via channels, controllers or any type of networking link, which
supports the transparent transmission of data to print processes that are resident in the device.
This service uses following TCP/UDP port:
TCP 5001: Used for transmitting data and printer control commands.
1-18-2 Potential Threats and Recommended Precautions
The Possibility of Acting as a Server for Relaying Viruses
The IPDS service treats all received data as print jobs and job control commands.
Theft of Username and Password
Interception of network packets: IPDS print can not be authenticated by the printer. Therefore, there is
no username and password in the IPDS print data.
Theft of Print Data
Interception of network packets: Using IPDS, print data is not encrypted. If intercepted by a third party, it
is possible to read.
Possibility of Successful DOS (Denial of Service) Attacks
The RICOH network device can detect a high frequency of logins and delay responses to the user’s
login requests. The device will also send an e-mail to the administrator. The device will create a log and
a message showing that the device is currently under attack will be displayed in Web Image Monitor.
1-18-3 Recommended Precaution
If a strict security policy is to be maintained, the IPDS service should not be installed. In addition, it can
be disabled and the port for this service can be completely closed using Web Image Monitor or the
mshell.
