Solved: FreeBSD as print server w/CUPS + samba + apsfilter

[Mike]

Greetings:

This post is a result of 2 days of thrashing trying to get FreeBSD (4.9) 
to act as a print server to Win2K/XP clients.  I have included links to 
a how-to that I wrote that includes a full install and configuration of 
CUPS and Samba so that local (connected to server) printers print 
locally, and so that that local printer(s) can then be shared (served) 
as network printer amongst Windows 2k/XP clients.

My original post on 5/21/2004 "Network printing question: apsfilter + 
samba over Win2k network" contained what I had accomplished, so far.

So... To make a long story short

I have apsfilter and CUPS and Samba installed and working.

The server prints to it's local (via parallel port) printer using either 
apsfilter or cups.

Serving that locally connected printer over a Windows network (to 
Win2k/XP clients) is accomplished with CUPS and Samba.

Here is the long version of the how-to:
http://www.ajl-tech.com/index.php?option=com_frontpage&Itemid=1
or 
http://www.ajl-tech.com/index.php?option=content&task=view&id=16&Itemid=31

Here is the short version, illustrated as general procedure (with in 
between steps removed).  This how-to assumes that the printer in 
question has a good driver available at www.linuxprinting.org.

Step 1. Install CUPS via ports and other apps + drivers

/usr/ports/print/cups
/usr/ports/print/gimp-print
/usr/ports/print/hpijs
/usr/ports/print/ghostscript-gnu
/usr/ports/lang/perl5

For each of the above: "make install clean"

Step 2. Get the proper driver (.ppd file) from www.linuxprinting.org and 
  copy it to the "/usr/local/share/cups/model" directory. For example:

chown root:wheel HP-LaserJet_4M-postscript.ppd
chmod 644  HP-LaserJet_4M-postscript.ppd
mv HP-LaserJet_4M-postscript.ppd  /usr/local/share/cups/model

Step 3. Get Foomatic.  You'll need the following 2 files:

http://www.linuxprinting.org/foomatic-rip
http://www.linuxprinting.org/foomatic-gswrapper

These files need to be moved to the right location with the right modes 
applied:

mv foomatic-rip /usr/local/bin
mv foomatic-gswrapper /usr/local/bin
cd /usr/local/bin
chmod 755 foomatic-rip foomatic-gswrapper

Step 4. Make sure Foomatic can be reached by CUPS:

Place a link in CUPS's "filter" directory at 
/usr/local/libexec/cups/filter: (note: the following is 1 line)

ln -s /usr/local/bin/foomatic-rip 
/usr/local/libexec/cups/filter/foomatic-rip


Important!!

CUPS will have installed its own versions of the commands "LP" "lpr" 
"lpq" "lprm" in the [/usr/local/bin] directory.  While BSD installs its 
own (original) versions of these commands in [/usr/bin].  For sharing 
this a printer to others across a network via Samba, we'll need to make 
sure to reference the CUPS version of “lp” “lpr” “lpq” and “lprm” (in 
/usr/local/bin).

Step 5. Configure the printer

Start CUPS: "/usr/local/etc/rc.d/cups.sh start"
Bring up CUPS via browser: "http://localhost:631"

Supply "Name" "Location" and "Description".  Then supply the printer 
model (the downloaded .ppd driver should be there as a choice).

Print a test page.  Congrats you should have local printing.

Step 6. Configure CUPS for network print service

Edit the "cupsd.conf" file.  Make the following configs:

Set your "broadcast" option for the LAN by  setting:
"BrowseAddress @LOCAL"

Set local access privileges, find the <Location /> section and:
<Location />
Order Deny,Allow
Deny From All
Allow From 127.0.0.1
Allow From 192.168.1.*
</Location>

This would allow anyone within the 192.168.1.* network to have access to 
CUPS.

Step 7. Install Samba via ports & Configure Samba

cd /usr/ports/net/samba
su
Password: ********
make install clean

Start Samba: "/usr/local/etc/rc.d/samba.sh start"

Note: make sure these ports are open on the server's firewall (for 
samba): port 139 (tcp), port 138 (udp), and port 137 (udp)

Modify the smb.conf file: Here is my working smb.conf file.

global]
         workgroup = workgroup
         printcap name = cups
         log file = /var/log/log.%m
         max log size = 50
         socket options = TCP_NODELAY
         netbios name = mango
         dns proxy = no
         load printers = yes
         security = share
         os level = 20
         printing = cups
         encrypt passwords = yes
         server string = Samba Server
[hp4m]
         printable = yes
         comment = hp4m for local network
         printer = hp4m
         use client driver = yes
         lprm command = /usr/local/bin/lprm P%p %j
         print command = /usr/local/bin/lp -d %p -o raw %s; rm -f %s
         lpq command = /usr/local/bin/lpq -P%p
         path = /var/spool/samba
         writeable = yes
         public = yes


Make sure that the “guest” user (nobody) is given access to the 
/var/spool/samba directory.

Also notice that the “lp”, “lprm”, and the “print” command reference the 
path to the CUPS versions of those commands.  I found this to be 
important. Referencing the FreeBSD (default) print commands will not get 
the job done!

Another important entry is the “use client driver = yes”.  If you don't 
include this setting, Windows 2000/XP clients will be able to print to 
the network hosted printer (HP4M), but they will complain about the 
“printer not being accessible”.

Well I hope this how-to is useful and will help others who have plans of 
replacing Windows 2000 servers with something "a little more durable".

I'm tired now but I've got a working print server.  It's time to buy 
beer and contemplate the universe...
