Ahhh.... This makes sense now! Try the following:
/* do a 'half close' on socket when sending job to remote printer */
{ "half_close", 0, FLAG_K, &Half_close_DYN,0,0,"=1"},
In the printcap file put:
lp:half_close@:...
or
lp:half_close=0:...
This will cause the TCP/IP connection to be 'closed' rather than
'shutdown'. The difference is that LPRng will be unable to monitor for
error messages coming back after the 'close' operation, but I gather
that you don't care about this.
