Intermate100 and Intermate101 Print Server Administration Manual 162
Services in “Input Control”: Raw Socket (= “Port 9100" = Reverse Telnet)
Example: TCP Port # 4 set to 49100
This example assumes that the print is to be directed to a logi-
cal printer (here called number 1) which performs pre-process-
ing, post-processing, and/or string substitution. The logical
printer definition also determines the choice of target printer.
Special ISPP port
Use the new [ISPP Port] page to change the port number for
this dedicated port from the default setting (9111), and/or to
specify “Output to”. Remember to “Save & Cont.” and then
“Reboot” to activate. Consider this port as an addition or an
alternative to using the usual raw socket port(s) to encrypt print
from an IBM mainframe host (running VPS/Secure from LRS).
Raw Socket Configuration Tip: Ensuring Bidirectional
Communication
If you want to exploit the potential for bidirectional communica-
tion, you need to check a page in the “Configurations > Output
Control” Section; the choice of pages depends on the choice of
Target Printer—local or network.
If you intend to print to the local printer (where the print server
is attached):
• Choose [Local Printer Parallel Port] in the
“Configurations > Output Control” section.
• The parameter “Parallel Port IEEE P1284 Negotiation
Mode” should be set to “ECP” or “Nibble”. If you choose
“Auto” and the result falls back to “Compatible”, you will
not get bidirectional communication.
• Make sure that the parameter “PJL Support” is
activated with the “Yes” radio button.
If you intend to print to a Network Destination, check the con-
figuration of the physical printer (Target Printer) on the [Net-
work Destination Option (NDO)] page. This printer must use
Raw as the transportation protocol. Note that the choice of port
number here has nothing to do with the print server port num-
ber value in step
