Default lpd printing in Current

Network printing broke in 5.2current about 2-3 months ago and I rode with it on the assumption that it would be fixed over a couple of upgrade cycles.

I think the error has something to do with detecting the Trendnet TE100-P1P print server.
Code:
Bear$ lpc status all
hp5l:
	queuing is enabled
	printing is enabled
	1 entry in spool area
	waiting for 9100@192.168.1.2 to come up
    :
	queuing is enabled
	printing is enabled
	cannot examine spool directory
I was using apsfilter and have also tried a ghostscript filter and a foomatic filter - all wait on 9100@192.168.1.2 to come up.

I briefly had trouble with printing *pdf files which went away with an upgrade. My last upgrade:
Code:
OpenBSD 5.2-current (GENERIC.MP) #2: Mon Dec 10 18:39:29 MST 2012
    deraadt@amd64.openbsd.org:/usr/src/sys/arch/amd64/compile/GENERIC.M

I really like the simplicity of lpr and would like to fix it rather then change over to cups.

Thanks in advance for any insights

Can you prove that you are able to connect to port 9100 on the printer's IP address? I'd use tcpdump(8) with telnet(1) or nc(1) and confirm you complete a TCP 3-way handshake. This looks like a networking issue, and I'd suspect your PF configuration of being the root cause if you cannot establish a connected state.

Logging PF blocks and passes will also aid your analysis of you cannot establish a connection to destination port 9100.

The above output is with pf=NO in my /etc/rc.conf.local. I returned to my last working printcap - the one with apsfilter. There an update for the base install that I will put in place and will test w/ and w/o pf. I'm relatively snow bound today and there is much to read on tcpdump and pf. I'll report back in a couple of hours.

The nc(1) -z option uses getservbyport(3) to test the connection. For TCP, it will report a message only upon successful 3-way handshake. From this, where there is no report:
Code:
Bear$ nc -z 192.168.1.2 80 
Connection to 192.168.1.2 80 port [tcp/www] succeeded! 
Bear$ nc -z 192.168.1.2 9100 
Bear$
and this:

I can jump to the conclusion that port 9100 is not open on the printer. I could be wrong, of course. I often am.

FYI: Port 9100 is the default for HP's JetDirect protocol, though of course many printers may use it for multiple protocols. You might try using the default port for lpd(8), which is 515. See /etc/services.

I reconfigured the print server and enabled port 81 for ipp:// printing and was able to successfully print with the old printcap

I have no clue what is going on but at least it works.
