How to install a HP Deskjet 845c under FreeBSD with CUPS, and how to make it 
work with samba.                                            
                                                            
( this is based on the how-to from http://www.freebsddiary.org/cups.php )
I installed the HP on a Compaq Deskpro EN 6400 with FreeBSD 4.7, so the USB procedure may
vary on your system. But i guess it would also work on older(or newer) systems.
Please make sure that your ports are up-to-date.

1.
 First you have to be sure that you have USB support in your kernel.
I use these options:

#USB things
device uhci
device usb
device ulpt

Compile the new kernel, and install it.(do not reboot, yet)

2.
Edit /etc/rc.conf, and add the following if its not there already:
usbd_enable="yes"
Make the device ulpt0 under /dev. (Skip it if it is already there)
cd  /dev && ./MAKEDEV ulpt0

3. Reboot, so the new kernel, and rc.conf takes effect.

4. (if using X11 skip this)
Add "WITHOUT_X11=yes" into /etc/make.conf

5.
Install ghostscript from ports with the following command:
cd /usr/ports/print/ghostscript-gnu && make install

6.
Install CUPS from ports with the following command:
cd /usr/ports/print/cups && make install distclean

7. (VERY IMPORTANT)
Disabling stock FreeBSD lpr.
a. Go to /usr/bin
cd /usr/bin
b. Backup print files.
tar cvfz default_print_bin.tgz lp*
c. Move compress file to a safe place. (Its up to you)
mv default_print_bin.tgz ~
d. Remove default print binaries.
rm /usr/bin/lp*
e. Make sure a buildworld not will install those files again by editing make.conf
NO_LPR=true

8. 
Copy cupsd.sh.sample to cupsd.sh, so cups will start at bootup.
cp /usr/local/etc/rc.d/cups.sh.sample /usr/local/etc/rc.d/cups.sh

9. CUPS can be administrered via webbrowser. I did that.
CUPS is looking for webadmin requests from localhost, so if you dont want that edit
 /usr/local/etc/cups/cupsd.conf and change 127.0.0.1 to the ip address for your workstation two places.

10.
Uncomment application/octet-stream in /usr/local/etc/cups/mime.types  and /usr/local/etc/cups/mime.convs  
Uncomment BrowseAddress @LOCAL in /usr/local/etc/cups/cupsd.conf.

12.
Start CUPS with "/usr/local/etc/rc.d/cupsd.sh start" , and check with ps aux that CUPS is running.
ps aux | grep cups

13.
Use your webbrowser to begin admin CUPS, with the following address: http://YOUR_SERVER_NAME_OR_IP:631/admin.
Add printer, and follow the directions. I used "USB Printer #1" in Device-section, "HP"and "HP DeskJet Series CUPS v1.1 (en) " for model/driver.
After doing that, try printing a testpage from CUPS webinterface. If it worked that is great, if not - try checking your cables, and such stuff, and do the printer installation one more time.

Now you should be able to print without any problems. Also try using lpr.
echo This is a test > ~/test_page.txt
lpr /~test_page.txt

To get Windows computer to use the printer, make sure you got a Samba server installed and working. Then edit /usr/local/etc/smb.conf. (Make sure Samba is compiled WITH CUPS support.)

A. ) Add to the [global] section:
printcap name = cups
use client driver = yes	(The Windows clients need the drivers for the printer. get it from hp.com)

B.) Add a [printers] section with this:

comment = All printers
path = /var/spool/samba
guest ok = no
read only = yes
printable = yes
browseable = no

Restart Samba, and your Window machines should be able to see, and install the printer.
