The easiest thing to do is replace eicat with a home-brew. It is
actually very simple. First experiment until you know how eicat is
being called (replace it with a #!/bin/sh shell script that echos
arguments to the console, for example).
The IMAGEN protocol is in the TCP/IP supplement to the printer
documentation. The easiest thing to do is:
for (;;) {
open connection to port 35 on printer
if succeeds then
send all data down the connection
if succeeds then break;
sleep for 1 minute
}
You can do better this with somewhat lower overhead by implementing
the UDP-based status protocol. In that case, probe the printer with
status packets until it indicates that it is running and accepting TCP
connections, then attempt one tcp connect. But the above will
certainly work well.
If you implement a "netpipe" like procedure that opens a socket to
port 35 or fails you can do the whole thing from a shell script.
When you are done, post your code to comp.sources.unix....
