No ideas, no special thoughts, just our configuration.
Yes, you are half right. The "rm=" field is a remote machine (either
IP quad dotted or DNS), the "rp=" field is the remote printer lpd
queue.
What happens is that if you have a Windows machine (or a Macintosh for
that matter) configured with the correct drivers for the printer you
are using you can normally get away with the "rp=raw" entry or even
with no "rp=" entry at all. If you are printing to such a printer from
your Linux box and you are using a text file you will probably get the
staircase effect (in this case either use a filter, try "pr file.txt
|lpr -Pprinter" or in some cases you can try to set another entry with
the same settings as the "raw" entry but with "rp=text" and of course
change the queue name).
O.K., that is enough for introduction. Our network layout:
One HP JetDirect 500X (print server) with one HP LaserJet 4P, one
DeskJet 870Cxi and one dot matrix printer, one HP LaserJet 5MP with
internal ethernet interface, one HP JetDirect 500X with a HP LaserJet
6MP and a DeskJet 560C, one Linux box server (Intel architecture)
about 20 PC (seven on one subnet) and half a dozen Macintoshes. All
this is on a Veterinary School and Hospital.
PC's are running mainly Windows 98, some Windows 95, one OS/2, NT
Workstation SP4 and RedHat 5.2 (it's mine and I multi-boot it with NT,
OS/2, W98, RH 5.2 and BeOS 3.2 just for testing, it isn´t a work box)
and one Windows 3.11. Mac's are running MacOS since 7.1PO-2 to 8.1.
The Linux server is running Debian 2.1, SAMBA 1.9.18p10 and
Netatalk+sun 4.12.
The net topology has seven PC and one print server on one subnet and
the remaining computers and printers on another. The Linux server is
on both nets.
Before going on let me say that the configuration we are using isn't
really needed since all print servers can work stand alone. We are
using it this way mainly for accounting and permission reasons.
Files to look at:
1. /etc/printcap
2. /etc/smb.conf (it may be /etc/samba/smb.conf) for PC's.
3. /etc/netatalk/papd.conf (it may be /etc/atalk/papd.conf or even
/etc/papd.conf) for Mac's (I could have set up the NetBIOS client DAVE
but it isn't freeware, it's slower and where's the fun of it?).

3. Our /etc/netatalk/papd.conf:
# start of /etc/netatalk/papd.conf
HP DeskJet 560C:\
:lp=dj560c-ps:\
:op=rlp:\
:pd=/var/spool/lpd/dj560c-ps/APPLE230.PPD:
# end of /etc/netatalk/papd.conf
o Now to create the corresponding spooler entries et al:
- - First one must create the directories under the /var/spool/lpd tree.
- - Second one has to create the acct and log files in each directory
(try "touch acct" and "touch log").
- - Third we must create the print filter (have a look at apsfilter).
- - Fourth, in case we are setting a print server for Mac's also, we
must get the PPD file corresponding to our printer (use APPLE230.PPD
for non PostScript printers) from the printer vendor or from
ftp.adobe.com.
- - Fifth, and also regarding the NETATALK suite we must create the null
device (use "mknod /var/spool/lpd/dj560c-ps/null c 3 1"). It is a
common mistake to use /dev/null since the lp deamon locks exclusivelly
the printer device and any other process accessing /dev/null will die
and or hang the system.
- - Next we must change the ownership of the print spooler files (try
"chown -R root.lp /var/spool/lpd/*").
- - Finally we must change the permissions for the files (maybe "chmod
660" for all and "chmod 770" for the print filter).
Now we start the print spooler (run "/etc/init.d/lpd restart" or maybe
"/etc/rc.d/init.d/lpd restart").
o Second step is to setup the SAMBA space:
We have created a user named rlp belonging to group samba for
accounting purposes.
- - First create the SAMBA spooler directory (try "mkdir -p
/home/samba/spool").
- - Second change the ownership of the directory (run "chown rlp.samba
/home/samba/spool")
- - Now we reload the SAMBA server (run "/etc/init.d/samba restart" or
maybe "/etc/rc.d/init.d/smb reload")
o Final step is to setup the NETATALK print deamon:
- - With the above steps done and a well configured
/etc/netatalk/atalkd.conf (it may be also located in the /etc/ or
/etc/atalk/ directories) we just have to reload it with
"/etc/init.d/netatalk restart" or maybe "/etc/rc.d/init.d/atalk
restart".
Just one final consideration. Although we have computers and printers
living in two diferent subnets and we maintained them in that manner
in our configuration, since we are passing all print jobs through our
Linux server which is on both subnets, we could easilly allow printing
to any printer regardless of which subnet it is on (this isn't
possible without the server spooling print jobs since we don't have
routes between the subnets).
Hope this example helps you in any way.
