Raw TCP/IP Printing
Raw TCP/IP is used to open a TCP socket-level connection over Port 9100, and stream a print-ready file
to the printer input buffer. It then closes the connection either after sensing an End Of Job character in
the PDL or after expiration of a preset timeout 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.

1.
In CentreWare Internet Services, click

9101
and Port 3 to
9102
.
5.
Next to Bidirectional, for each active port, select
Enabled
.
6.
Next to Maximum Connections per Port, for each active port, type a number from 1 through 32.
7.
Next to End of Job Timeout, for each active port, type a time in seconds from 0 through 1800.

2.
Under Connections, set the following:
−
Set the Maximum Connections per port between
1–32
. The default port value is 32.
−
To allow concurrent jobs to process for each port connection, type a number between
0–500
jobs in each port. Type
0
to allow unlimited concurrent jobs.
−
To limit the number of jobs that are active for each port connection, type a number between
0–32768
. Type
0
to allow unlimited number of active jobs.
3.
Under Job Boundary Determination:
−
Type the End of Job Timeout between
0–1800
seconds to specify the amount of time to pass
before a job processes with an End of Job character. The default time is 300 seconds.
Type
0
to disable end of job detection by timeout.
4.
Under Backchannel Data:
−
Enable
Backchannel Data Transmission to Client
, then, enable
Out of Order Backchannel
