Ralph,
Perfect. That solved my problem. I created the following patch to ifhp.c.
*** ifhp.c.old Wed Feb 25 10:56:25 2004

Snmp_dev, Device, GET_HASH_STR_OBJ(Model, "lp", MEMINFO ) );
! if( ISNULL(Snmp_dev) ) Snmp_dev = Device;
if( ISNULL(Snmp_dev) ) Snmp_dev = GET_HASH_STR_OBJ(Model, "lp",
MEMINFO );
if( (s = safestrchr(Snmp_dev,'%')) ) *s = 0;
LOGMSG(LOG_INFO)"snmp device '%s'", Snmp_dev );

}
DEBUG1("main: start snmp_dev %s, Device %s, :lp=%s",
Snmp_dev, Device, GET_HASH_STR_OBJ(Model, "lp", MEMINFO ) );
! if( ISNULL(Snmp_dev) )
! if ( ! ISNULL(Device) )
! Snmp_dev = safestrdup(Device, MEMINFO);
if( ISNULL(Snmp_dev) ) Snmp_dev = GET_HASH_STR_OBJ(Model, "lp",
MEMINFO );
if( (s = safestrchr(Snmp_dev,'%')) ) *s = 0;
LOGMSG(LOG_INFO)"snmp device '%s'", Snmp_dev );

Hello!
I encountered the same problem, and tracked it down to the ifhp source,
I think. Of course, I could be wrong ...

Here the device appears as assigned in your "lp=" printcap entry.

Here the device to use for SNMP is determined (originally it was NULL
because you have not included an "snmp_device" parameter in your "ifhp="
line.

And here the printer device port number has magically disappeared.

Now look at the source (ifhp.c line 394ff):
DEBUG1("main: start snmp_dev %s, Device %s, :lp=%s",
Snmp_dev, Device, GET_HASH_STR_OBJ(Model, "lp", MEMINFO ) );
if( ISNULL(Snmp_dev) ) Snmp_dev = Device;
if( ISNULL(Snmp_dev) ) Snmp_dev = GET_HASH_STR_OBJ(Model, "lp", MEMINFO
);
if( (s = safestrchr(Snmp_dev,'%')) ) *s = 0;
LOGMSG(LOG_INFO)"snmp device '%s'", Snmp_dev );
If we have a non-null Device but not a non-null Snmp_dev, the former is
assigned to the latter, and then the port number (if any) is removed.
At that time, Device and Snmp_dev point to the same string, so Device
loses its port number as well.
It may help to change the assignment:
Snmp_dev = Device;
to:
Snmp_dev = safestrdup(Device, MEMINFO);
I have other problems with mit HP test printer, so I cannot test the
effect right now, but you may want to give it a try.
Or as a workaroung, add "snmp_dev=wfd-color3" to your "ifhp=" config
line.

Ralph R��ner
