I am looking for a printserver with an old postscript-printer (Lexmark E322) and found http://wiki.openwrt.org/doc/howto/printer.overview

p910nd says at http://wiki.openwrt.org/doc/howto/p910nd.server usb.essentials is needed and cups - http://wiki.openwrt.org/doc/howto/cups.server needs usb.essentials too. But http://wiki.openwrt.org/doc/howto/usb.essentials says: "Most images offered on the OpenWrt download page, come with the basic USB support already included, if yours doesn't, you are right here."

An external-USB-drive is recognized, so do I need to install usb.essentials and which printer-server to you recommend?

I want to print from Clients with Linux 32 and 64 bit (Ubuntu 12.04, Opensuse 12.2), XP Home 32bit, Win7 Prof. 64bit.

Below you find some info re installed packages and available space.

There is no way you are going to install cups on the internal memory of your router, simply not enough space.

You can put the overlayfs on a usb stick and have more space that way (see pivot root in the wiki).
So I would try p910nd in this case, also windows and linux can print directly to it. (for linux you do need cups, but you needed that anyway to connect a network printer)

Thanks, so I have to try http://wiki.openwrt.org/doc/howto/p910nd.server

I did _not_ install usb.essentials!
But kmod-usb-printer and p910nd

How can I search for the printer (Lexmark E322), which is connected to the openwrt-device in a shell or whatever?

I am not sure, what I need else and what not, as described at http://wiki.openwrt.org/doc/howto/p910nd.server

How can I do a test using Linux?

/dev/lp0 is your printer. You need to point your printer setup to the router's IP and find out which protocol to use (it's often RAW I believe). Been a while since I set up a networked printer. You'll still need to install the drivers (usually not necessary on Linux, but you will need to on Windows). Usually it involves installing the printer locally first.

Well for starters I think option enabled should be 1
option port is new to me, but since there is only one printer connected I would go with 9100 (default tcp port)

you don't have to do anything with /dev/lp0 on a client you are connecting to the printer, of course it should be a valid printer on the server. But it is working because the log that contains it was allready posted.

To install the printer in windows, you need to select local printer and create a new port and select tcp/ip and the protocol is indeed RAW.

And in linux you just simply can install it under cups.

tutorial for linux: http://www.noah.org/wiki/Printing_CUPS_lpr

Of course in both cases you do need the driver that is needed for the printer. the server p910nd will simply forward the data from the network port to the printer and vice versa, nothing more.

for cups you need: socket://hostname:port

Let's talk about Linux first, Windows is not so important. I mentioned it, because I thought it could be interesting to choose the privterserver. "option enabled       1" was set and the TL-WR1043ND was rebooted.

I have to say, that I could already print with the linux pc, when the printer was connected to an avm fritzbox via usb. To get it work with avm I had to execute "lpadmin -p E322 -E -v socket://192.168.178.1:9100 -m foomatic-db-compressed-ppds:0/Lexmark-Optra_E312-Postscript.ppd" I used E312 because there is no driver for E322 and it works.

A firewall problem?

It looks like port 9100 is not open, although I added the rule from http://wiki.openwrt.org/doc/howto/p910nd.server

By default the router doesn't block anything lan side. (also not in your case).

is the daemon p910nd actually started?
have you changed the port and enabled in the config?
on the router you can see the listening tcp ports with netstat -tnl
add a p as well to see what programs acompany the ports

(protocol is the same as the fritzbox)

I found 2 things: the daemon was not started and when I start it manually I see another port.

netstat -tnl
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address           Foreign Address         State

tcp        0      0 0.0.0.0:9109            0.0.0.0:*               LISTEN      
tcp        0      0 0.0.0.0:53              0.0.0.0:*               LISTEN      
tcp        0      0 0.0.0.0:22              0.0.0.0:*               LISTEN      
netstat: /proc/net/tcp6: No such file or directory

I started it with "/etc/init.d/p910nd restart". How do I start the server automatically after a reboot?

Why do I get port 9109 instead of 9100?

 cat /etc/config/p910nd
config p910nd
    option device        /dev/lp0
    option port          9100
    option bidirectional 1
    option enabled       1

to start the server automatically after a reboot type
/etc/init.d/p910nd enable

why it does start on 9109 not a clue, what happens if you drop 'option port' all together from the config?
because mine doesn't seem to need it. (after looking at my config) but the rest is identical.

edit: Lol, I think I know where the 9 came from, try to change the port number to 0 again, and see what happens (or drop the whole line)

Any ideas?

Well, I don't think the problem is at the router at this point. Because it is a rather simplistic server. It just forwards data.
(other then a cups server, that can do some more interesting things).

what does the cups error log (on the client computer) tell you? it could yield some more info.

(Last edited by FriedZombie on 5 May 2013, 22:35)

If I open a text-editor an the pc (client) I see a printer named "E322TP" (see error above!) and if I click on print, it prints garbage.

(Last edited by linuxuser on 5 May 2013, 22:52)

Well I think the printer will work flawlessly on your windows computer.

At least remove line 16 of your /etc/cups/cupsd.conf
it doesn't work there anymore after a security update, systemgroup is migrated to cups-files.conf
(other then making a mess of the logs not the issue).

For the other issue try removing the printer and readd it.
Not sure if it makes a difference in this case

lpadmin -x E322TP && lpadmin -p E322TP -E -v socket://192.168.178.50:9100 -m foomatic-db-compressed-ppds:0/Lexmark-Optra_E312-Postscript.ppd

It could be the result of that the printer took longer then 30 secconds to install. (see a bug report somewhere on cups) Had the issue somehwere in the past as well.

edit: the driver shouldn't be the issue in this case.
If all else fails, you could still and try if your windows computer works better.
see http://dougmunsinger.com/posts/adding-h … ws-xp.html
(jetdirect is the raw protocol, and if no port is specified it defaults to 9100)

edit2: or try to set it up on your other linux computer, same way

I will give you feedback after I could test it, at the moment I have access to only 1 linux pc. Thanks for you suggestions.

The path changed, a folder ppd was put in between. Now it works with Linux. lpinfo -m shows the correct path already ;-), but I used a path, which I found in a forum and worked a long time ago.

#doesn't work
lpadmin -p E322TP -E     -v socket://192.168.178.50:9100 -m foomatic-db-compressed-ppds:0/Lexmark-Optra_E312-Postscript.ppd

#works:
lpadmin -p E312-PS -E    -v socket://192.168.178.50:9100 -m foomatic-db-compressed-ppds:0/ppd/foomatic-ppd/Lexmark-Optr312-Postscript.ppd
lpadmin -p E321-ljet4 -E -v socket://192.168.178.50:9100 -m foomatic-db-compressed-ppds:0/ppd/foomatic-ppd/Lexmark-Optra_E321-ljet4.ppd

I tried a text-only page and this is ok. Don't know, when I can test windows. Thanks for your help!

If your printer is supported by Google Cloud Print I'd use that :-)

Glad you got it to work, but if it works from linux it does work from windows as well because they use the same protocol to transfer the data.

Also stupid I missed that slight path change as well
