Raw TCP/IP Printing
Raw TCP/IP is a printing method used to open a TCP socket-level connection over Port 9100, to stream
a print-ready file to the printer's input buffer. It then closes the connection either after sensing an End
Of Job character in the PDL or after expiration of a preset time-out value. Port 9100 does not require
an LPR request from the computer or the use of an LPD running on the printer. Raw TCP/IP printing is
selected in Windows as the Standard TCP/IP port.
Basic Settings
Notes:
• TCP/IP must be enabled before Raw TCP/IP Printing is enabled.
• Raw TCP/IP printing is selected in Windows 2000 as the Standard TCP/IP port.
• If your printer is locked, you must log in as a system administrator. For details, see
Accessing CentreWare IS on page 17.
1. In CentreWare IS, click Connectivity > Protocols > Raw TCP/IP Printing.
2. Select Enabled to enable the protocol.
3. Ensure that the TCP Port Number is set to 9100 for Port 1.
Note: To emulate HP JetDirect EX Plus 3, set Port 2 to 9101 and Port 3 to 9102.
4. Select Enabled for Bidirectional communication.
5. Ensure that Maximum Connections per port (1-32) for each port is set to the default value of 8.
6. Set the End of Job Timeout to the desired number of seconds between 0-1800 before processing
a job with an End of Job character. The default time is 300 seconds.
7. Select Enabled for PDL Switching to allow the printer to automatically switch between multiple
supported PDLs within a single job.
Note: PDL Switching should normally be disabled.
8. Click Apply to accept the changes or Undo to retain the previous settings. To set all fields to
printer default values, click Default All.
9. Click OK.
Advanced Settings
Additional Raw TCP/IP Printing options can be specified in the Advanced page. These include:
1. Connections
• Total Job Limit per Connection: Type a value between 0 and 32768 to limit the number of
jobs that can be active for each port.
• Maximum concurrent connections
• Maximum concurrent jobs: Type a value between 0 and 500 to specify the maximum
number of concurrent jobs. A setting of 0 allows unlimited concurrent jobs.
2. Job Boundary Determination
•Enable Control D Marks End of PostScript Job if you want the Control D character to be used
to indicate the end of a PostScript print job.
