lpr printer setup

[shep]

I'm struggling with setting up and HP 5L laserjet on a trendnet print server.
I have the printserver assigned a static address 192.168.1.2 that works in cups.
The server name is

PS-8B4C0D

with port name

P1

My /etc/hosts

192.168.1.2 PS-8B4C0D

My /etc/hosts.lpd

PS-8B4C0D

One thing I am confused by is the gutenprint driver is supposed to have a builtin ghostscript filter. I have ghostscript, foomatic-filters and foomatic-db installed. The pkg-readme for foomatic-filters suggests a printcap line if=/usr/local/bin/foomatic-rip: but I'm not sure I need this if the driver

HP-LaserJet_5L-ljet4.ppd

has a builtin filter?


When I #lpc start hp5l I get an error message that it cannot connect.
I tried generating a printcap with apsfilter but am not clear on the fields rm and rp (tried numerous iterations). I tried editing the printcap in /usr/local/share/doc/pkg-readmes/foomatic-filters (from C64 to HP 5L) and found two pertinent posts in this forum, both on local lpt printers.

Penultimate question: Since it is a remote printer I would not think there would be any permission issues (I am a member of wheel).

Ultimate question: Any one have a printcap that is close to my configuration they can post?

Thanks in advance

I still have these notes I wrote down 4 years ago. But I think my situation was a little bit different then yours, so I am not sure it will help

I installed apsfilter on a local OpenBSD box with an USB HP deskjet printer so it could be my print server.

The host name of the print server is 'protogoras.utp.xnet'.
To be able to print from my OpenBSD workstation "zeno.utp.xnet' I have this /etc/printcap

j65nko@zeno[~]cat /etc/printcap

#       $OpenBSD: printcap,v 1.4 2003/03/28 21:32:30 jmc Exp $

#lp|local line printer:\
#       :lp=/dev/lp:sd=/var/spool/output:lf=/var/log/lpd-errs:

lp|rp|remote line printer:\
        :lp=:rm=protogoras.utp.xnet:rp=lp:sd=/var/spool/output:lf=/var/log/lpd-errs:

On 'protogoras.utp.xnet' I have added ""zeno.utp.xnet'" to the file /etc/hosts.lpd.

j65nko@protogoras[~]cat /etc/hosts.lpd
#       $OpenBSD: hosts.lpd,v 1.2 1996/07/20 00:28:28 deraadt Exp $
# as described in lpd(8), place one legal access hostname per line
zeno.utp.xnet

On both the workstation and the print server I have enabled lpd

j65nko@protogoras[~]grep lpd /etc/rc.conf.local
lpd_flags=""

Please note this part of the lpd(8) man page

     lpd performs reverse DNS lookups on network clients.  If a client host-
     name cannot be determined from its IP address, the print request will be
     silently dropped.  This is important to note when debugging print prob-
     lems in dynamic address environments.

You are mixing awfully lots of things. PPDs are not drivers. Those are PostScript Printer Description files. foomatic-rip filter uses them to decide which driver to call. If the driver is Guthenprint it calls it. Ghostscript is just another collection of printer drivers.

Apsfilter is as the name said just another filter (parse file which you sent to printer, calls appropriate program to convert it to PostScript and then calls appropriate driver if the printer doesn't have built in PostScript interpreter). foomatic-rip does the same. So make your pick.

Here is my printcal for the local printer.

lp|Lj4L|HP Lj4L:\
        :lp=/dev/lpt0:\
        :af=/etc/foomatic/HP-LaserJet_4L-ljet4.ppd:\
        :if=/usr/local/bin/foomatic-rip:\
        :sh:sd=/var/spool/output:\
        :lf=/var/log/lpd-errs:

Now your printer is remote which means that you will replace line

:lp=/dev/lpt0:\

with something like

:lp=:rm=192.168.2.xxx:\

Permission problem indicates two things

1. Your spooling directory

sd=/var/spool/output

doesn't have appropriate permission 755.


2. Secondly if your printer server is on another machine you have to edit

/etc/hosts.lpd

in that machine and enter IP address of the client machine (machine that you are trying to print from).

Finally if you are using some kind of stand alone printer server for all I know that thing might be speaking only IPP protocol which lpd daemon doesn't speak.

PS. I forgot to add that you obviously have to pass the traffic in your firewall out of your printer client and also server has to be able to get it. So you have to open 515/tcp port on the server.

[shep]

It is a stand alone print server that continues to work well with cups
One confusing aspect is the printcap in an Arch Linux running cups reads

hp5l|H-P 5L Laserjet:rm=Bear:rp=hp5l:

Bear is the name of the Arch Linux box. Bear also prints via network protocol and in cups I set the network option as

http://192.168.1.2/P1

I redid the permissions on /var/spool/output.

My /etc/printcap

hp5l|HP 5L Laserjet:\
:lp=:\
:rm=PS-8B4C0D:\
:rp=P1:\
:af=/etc/foomatic/HP-LaserJet_4L-ljet4.ppd:\
:if=/usr/local/bin/foomatic-rip:\
:sh:sd=/var/spool/output:\
:lf=/var/log/lpd-errs:

Also tried :rm=192.168.1.2:\ and rm=PS-8B4C0D.home.yak:\

Still get an error message that lpc start hp5l will not connect.

[J65nko]

rm is the remote printer. It needs either a hostname that your box can resolve to an IP address or just an IP address.
If you run dig PS-8B4C0D.home.yak do you get the IP address 192.168.1.2 as answer?

Most Unix programs produce postscript output. Unfortunately most printers don't understand postscript. In those cases you need a filter that converts the Postscript file to a file with the native printer commands. Then the file with the native printer codes will be sent to the (remote) printer.

But if the (remote_ printer understands Postscript, you don't have to deal with any filters at all. Just a correct entry for rm will do.

Did you see http://netbsd.org/docs/guide/en/netbsd.html#chap-print ?

[J65nko]

I entered this in my printcap on 192.168.222.20 although 192.168.222.244 doesn't have anything like a printer configured

rp|remote line printer:\
        :lp=:rm=192.168.222.244:rp=lp:sd=/var/spool/output:lf=/var/log/lpd-errs:

Now a status check

$ lpc status
rp:
        queuing is enabled
        printing is enabled
        3 entries in spool area
        waiting for 192.168.222.244 to come up

If I do lpr -Prp <quotes.txt I get

$ lpc status           
rp:
        queuing is enabled
        printing is enabled
        4 entries in spool area
        waiting for 192.168.222.244 to come up

One more job in the spool area..

My firewall on my box is blocking port 515, that is why it is waiting ...

04:51:48.710783 rule 20/(match) block out on re0: 
192.168.222.20.925 > 192.168.222.244.515: S 3733580883:3733580883(0)
 win 16384 <mss 1460,nop,nop,sackOK,nop,wscale 0,[|tcp]> (DF)

What is the output on your box of lpc status ?

I appreciate the help

Which model TRENDnet print server do you have See http://www.trendnet.com/products/products.asp?cat=46#26 ? (Why do I have to do your homework )

Can you, install or reconfigure apsfilter with the HP 5 printer, temporarily connected to your OpenBSD box to get that working first?

I have an howto (still in alpha stage) of installing apsfilter and configuring it for a locally connected USB printer. It has screenshots of the complete apsfilter configuration. That is the good news. The bad news : it is from July/August 2007
If needed I can post/attach it here.

[shep]

I have the TE100-P1U (Version v2.xR) printserver.

It has worked well for years using CUPS.

There is no urgency to get this done - it is a learning exercise for me and I usually resort to the forum when the man pages, pkg-readmes and FAQ's and my intellect fail.

The FreeBSD handbook has an extensive entry on setting up printing. Is lpr consistent across the various BSD's to review this. I do not have the background to assess the applicabilty of the FreeBSD information to OpenBSD but I will read with the idea of understanding the processes involved.
http://www.freebsd.org/doc/en_US.ISO.../printing.html

[shep]

Some Progress, the lpd daemon does not appear to be starting. When I manually started it I was able to 'lpc start hp5l'. I'm not sure why it does not start at boot but will try a more explicit 'lpd_flags=YES'

# ps -auxU daemon
USER PID %CPU %MEM VSZ RSS TT STAT STARTED TIME COMMAND
# lpd
# ps -auxU daemon
USER PID %CPU %MEM VSZ RSS TT STAT STARTED TIME COMMAND
daemon 27063 0.0 0.1 400 856 ?? Ss 3:29PM 0:00.00 lpd
# lpc start hp5l
hp5l:
daemon started

# cat /etc/rc.conf.local
ntpd_flags="-s" # enabled during install
xdm_flags= # enabled during install
ldp_flags=""

I just now see the typo ldp -> lpd
Now I'm also dealing with permission problems.

$ lpr -P hp5l print_test.txt
lpr: /var/spool/output/tfA004Test.home.yak: Permission denied

# ls -al /var/spool/output
total 12
drwxr-xr-x 2 root daemon 512 Mar 1 14:42 .
drwxr-xr-x 12 root wheel 512 Mar 1 11:12 ..
-rw-rw---x 1 daemon daemon 4 Mar 2 15:31 .seq

The freebsd handbook is good to get a general idea about the lpd printing process.

[J65nko]

IMHO http://netbsd.org/docs/guide/en/netbsd.html#chap-print is also excellent.

Some general information and links can be found in http://en.wikipedia.org/wiki/Line_Pr...aemon_protocol

RE: lpd start in "/etc/rc.conf.local"

After I made a similar typo/mistake I made it a habit to use grep on the default rc.conf

 $ grep lpd /etc/rc.conf

Success. I updated the firmware on the printserver (may not have been necessary) and found that the server had an extra port 81 for 'ipp://'. Oko's post indicated this was not supported by lpr but I found out that lpr does support port 9100 (HP jetdirect). A quick check showed the printserver to also support that port. I setup a quick printcap using :lp=9100@192.168.1.2 without a filter and the printer made printer noise but generated empty pages!
I went back tried to enter in 9100@192.168.1.2 in the apsfilter ./SETUP but it would not print a test page. I install the apsfilter printcap anyway and edited :lp=:\ -> lp:9100@192.168.1.2. and removed the :rm and rp entrys.
