Hello Keith !

Ok .. first and to answer the topic: Yes, I can, and it has been that 
way since day 1 with FreeBSD in here.

Your printed seems  to be supported by hplip ...

Maybe you should have taken a look at the hplip post install message ...
Here, take a look at this:

[gonz...@inferna ~]% pkg_info -xD hplip
Information for hplip-2.8.2_3:

Install notice:

**************** UPGRADE FROM 1.X NOTICE *****************

NOTE: If you are upgrading from 1.x you will need to
change your devfs ruleset as hpiod is now gone, so remove
it from you rc.conf.  The printer communication now runs
through cupsd.  You will need to make the devfs ruleset
changes to allow cups to access the usb bus and ugen
devices so that it can enumerate the printers.  You will
also need to update your hplip.conf.  See the instructions

**************** UPGRADE FROM 1.X NOTICE *****************

Add the following to your rc.conf:


So all you have to do if you have a custom ruleset setup
is add the following to that ruleset in devfs.rules:

add path 'usb*' group cups
add path 'usb*' mode 0660
add path 'ugen*' group cups
add path 'ugen*' mode 0660

If you have never setup devfs.rules please read the
manpage and see:

The printer MUST attach as a ugen(4) device.  This means
that you must NOT have "device ulpt" in your kernel and
ulpt must NOT be loaded as a kernel module.

If you are seeing device connection errors restart the
printing chain with the following command.  NOTE: It MUST
be restarted in the stated order.
%%PREFIX%%/etc/rc.d/hpssd restart && \
%%PREFIX%%/etc/rc.d/cupsd restart

If upgrading from a version < 2.7.9 copy the new
hplip.conf.sample config.
cp %%PREFIX%%/etc/hp/hplip.conf.sample \

If you are still having problems check:
If you are still having problems send the relevant part
of your /var/log/messages, console output from the hp-*
utility that you are trying to run, and your rc.conf +
devfs.rules files and the output of "ls -l /dev" to the
[gonz...@inferna ~]%

So .. basically .. get rid of "ulpt" ... recompile your kernel if you 
have to, but get rid of it .. the printer MUST attach as a ugen(4) 
device ...

Plug your printer in, turn it on and .. add this lines to devfs.rules 
(change the "[system=10] " to suit your needs if you have to)

add path 'usb*' group cups
add path 'usb*' mode 0660
add path 'ugen*' group cups
add path 'ugen*' mode 0660

after that, issue the following commands:

cp /usr/local/etc/hp/hplip.conf.sample /usr/local/etc/hp/hplip.conf 
/etc/rc.d/devfs restart 
/usr/local/etc/rc.d/hpssd start 
/usr/local/etc/rc.d/cupsd start 

log in to the cups config page and follow the steps to configure your 
printer ...

when prompted for a printer URI, make use of hp-makeuri to determine 
what URI you should use .. I use it like this:

hp-makeuri printer_serial_number

and it will return something along this way:


feed that to the URI field and then move on to choose the ppd file which 
you'll be able to find under /usr/local/share/ppd/HP ...

And that's about it ..

As mentioned in the after install notes, forget ulpt ... hplip needs the 
printer attached using ugen. ultp shouldn't even be loaded in the 
kernel as a module !

Add this lines to devfs.rules (change the "[system=10] " to suit your 
needs if you have to)

add path 'usb*' group cups
add path 'usb*' mode 0660
add path 'ugen*' group cups
add path 'ugen*' mode 0660

then issue the following command:

/etc/rc.d/devfs restart

You shouldn't need any dll at all .. :
[gonz...@inferna ~]% ls /usr/local/share/ppd/HP/ | grep officejet_4100 | 

that's all you need ...

I have this three lines on my /etc/rc.conf file:

After adding those lines to your /etc/rc.conf file .. theoretically .. 
nothing ... hpssd and cupsd should be enabled by default on every 
boot ..

Hope that helps !
