Network Protocols
The printer will work with any system having TCP/IP support. It will
not work with Netware IPX, Microsoft NetBEUI protocol, Appletalk,
LAN Manager, or Microsoft Windows Network.
Network Applications
CognitiveTPG Ethernet equipped printers utilize TCP/IP for their
communications protocol. The printer acts as a remote host, providing
the following application level interfaces:
LPD
The printer acts as an LPD (Line Printer Daemon) to accept print jobs,
and will accept one connection at a time for incoming data. A second
connection is available for status checks. This is the recommended
method for sending print jobs to the printer.
You must use TCP port 515 to connect to the printer using LPR.
TFTP
A TFTP (Trivial File Transfer Protocol) daemon implemented on top of
the UDP (User Datagram Protocol) provides a fast way to upload new
code and objects to the printer. You can use TFTP in conjunction with
bootp/DHCP to automatically update the printer firmware or stored
objects.
Connect to the printer using UDP port 69 for TFTP operations.
RTEL
An RTEL (Reverse Telnet) daemon is implemented on top of TCP. This
is a user definable TCP port, allowing a direct socket connection to the
TCP port without data processing. Connection via RTEL is effectively
the same as sending data directly to the printer’s serial or parallel
port.
The default RTEL port is 9100.
