A comment: When pasting here computer commands and such, please use a
CODE BLOCK, so that the forum software doesn’t do silly things like
converting URLS to tiny urls or otherwise hide or alter the commands you
entered. You get them by clicking on the ‘#’ button in the forum editor.

You can increase cups log verbosity. In “/etc/cups/cupsd.conf” change
“LogLevel debug”, and restart the service:


systemctl restart cups.service

Then try printing and inspect the cups logs.

I’m not familiar with Lexmark hardware, but just to get the background to this, I presume you started by installing the driver from the Lexmark site, and downloaded lexmark-inkjet-legacy-wJRE-1.0-1.x86_64.rpm.sh.tar.gz’ or similar? I wonder if the install completed? I note that part of the install adjusts the firewall to open UDP port 5353. Just in case this failed, you might want to check this port, or disable the firewall

How are you connected? (Ethernet cable, USB,…?)

deano_ferrari · July 22, 2014, 11:46am

I also note that there are two versions of the proprietary driver available - one with JRE, and one without. Hopefully, a Lexmark user can chime in with further advice. You may need to obtain support via Lexmark since it is a proprietary driver…

deano_ferrari · July 22, 2014, 11:54am

I also note (following a quick check of CUPS) that there is a postsctipt driver available for the Lexmark Pro800-Pro900 Series. Have you tried using that (albeit that it may only provide basic functionality)?

hello,

i had installed the following driver which is usually ok :
Name: lexmark-inkjet-legacy-wJRE
Version: 1.0-1
Arch: i386

i opened with a new rule in firewall for udp 5353
i have changed log level to debug, here are some quotes from the error logs if this helps :

Well, there seems to be a communication issue with the printer as reported here:

E [22/Jul/2014:15:24:21 +0200] [Job 149] Erreur d'imprimante. L'imprimante ne peut pas communiquer avec l'ordinateur.

and the the following CUPS message

(/usr/lib/cups/backend/lxhcp) stopped with status 1.

which might suggest that the printer has paused, or some other error condition is present perhaps. What is shown about the printer in /etc/cups/printers.conf? Check the status via the CUPS web interface

http:localhost:631/printers

Maybe it can resumed from there if necessary.

BTW, you didn’t tell us how this printer is connected (ie ethernet, usb…)

manchette_fr · July 22, 2014, 10:24pm

hi,

the printer is connected with an Ethernet cable to the local network, in cups the status says ‘idle’ (not busy)

here’s the file content you asked for :

deano_ferrari · July 22, 2014, 10:59pm

Okay, that all looks good. How did you configure your printer? Did you use the ‘/usr/local/lexmark/legacy/bin/.scripts/lxtoolbox’ utility? Were you able to print a test page during this process?

What happens when you try to run the backend manually?

/usr/local/lexmark/legacy/bin/lxhcp

It may take several seconds for its query to complete or timeout. Do you get any output? If not, maybe there is no packets getting to the printer (ie router or firewall issue perhaps).

manchette_fr · July 22, 2014, 11:22pm

to install i followed the gui guide provided during the driver install, i have not really added specifical rules but for the error policy which i set to ‘retry job’.

manually it says “command not found” :


linux-opensuse131:~ # /usr/local/lexmark/legacy/bin/lxhcp
/usr/local/lexmark/legacy/bin/lxhcp: line 1: fabrice@linux-opensuse131:~:: command not found


linux-opensuse131:/usr/local/lexmark/legacy/bin # ls
.scripts  demond  lxhcp  printfilter  rootme  slogcap  surunner

deano_ferrari · July 22, 2014, 11:36pm

Sorry, the backend is located in /usr/lib/cups/backend/, so try

/usr/lib/cups/backend/lxhcp

deano_ferrari · July 23, 2014, 12:17am

I note from examining your printers.conf, that the printer is referenced by its discovered hardware MAC address

DeviceURI lxhcp://00200067AB79

It is possible to use the IP address instead (assuming it has been configured previously). If you have a Windows environment, you might want to consider setting up the printer address to match your network environment. Having said that, the lxhcp backend should be able to cope with either method (as long as the communication packets are able to get to the printer).

In an effort to help, I ran the setup utility (as root) using

/usr/local/lexmark/legacy/bin/.scripts/lxtoolbox

and note that there is an option to ‘Let me specify an IP address’, then once the correct ‘model’ is chosen it is possible to add an IP address manually. Of course, I don’t have the printer, so can’t really test further.

manchette_fr · July 24, 2014, 4:07pm

hi,
yes, it’s possible to set an ip, but while installing it’s as easy to select the printer’s name in the list provided, i guess it should be ok.

does it make a big difference ?

deano_ferrari · July 24, 2014, 9:16pm

Well, the driver is capable of using layer 2 communication (assuming the network is transparent at that level), but sometimes layer 3 (using IP addressing) is necessary. For example, I’ve observed strange behaviour when a printer is connected to router via wired ethernet, and a PC is connected via wireless link on the same network. It ‘appears’ to be a communication-related issue, but I guess the setup utility was able to discover the device in the first place. I think it is worth perusing (but you’ll probably need to configure it via Windows first).

If communication was working, running the backend manually should have produced some output (following communication with the discovered printer)

/usr/lib/cups/backend/lxhcp

From what I’ve read, I think it uses some hybrid mDNS-type discovery broadcast.

I don’t want to confuse you, but there are some good workarounds mentioned in this Puppy Linux forum

manchette_fr · July 26, 2014, 7:20pm

actually i know there 's something wrong but i’d like to understand how come when it was working a few days ago.
“/usr/lib/cups/backend/lxhcp failed” in cups shows printer can’t be reached but i don’t get why.

i already had port 5353 open and added mDNS service in the firewall but it does not help.

deano_ferrari · July 26, 2014, 11:43pm

You didn’t mention that before. Can you make sure that any existing print jobs are cancelled?

“/usr/lib/cups/backend/lxhcp failed” in cups shows printer can’t be reached but i don’t get why.*

Me neither, but I have been encouraging you to run the backend manually with the printer connected and report back with the output (if any). If it fails, we have a communication issue. Do you have any other machines that can reach this printer successfully?

manchette_fr · July 27, 2014, 6:36pm

Hello

Actually yes, i should have said it earlier.
I can see the results in Cups, i have the list of tasks and i had to erase each task not successfull ( for if not an error message keeps coming all the time) .

When i run manually i have no result in console

/usr/lib/cups/backend/lxhcp

Here’s what i have in the error log just after running the code above : http://susepaste.org/502455

I have a windows 8 machine nearby, on ethernet too and this one prints ok.

One quick way of doing that via CLI, would be

cancel -a

/usr/lib/cups/backend/lxhcp

Okay, well your printer should be annunciated (by MAC address) when it is run. You might try disabling your firewall temporarily

systemctl stop SuSEfirewall2.service

then run the command again. If it works, we a have a firewall issue to fix.

I couldn’t see anything unusual in the log.

I have a windows 8 machine nearby, on ethernet too and this one prints ok.

Good to know.

I guess you could use it (or via the printer front panel perhaps) to configure a valid IP address. Then try using the lxtoolbox utility to try an reconfigure for CUPS…

/usr/local/lexmark/legacy/bin/.scripts/lxtoolbox

manchette_fr · July 29, 2014, 4:09pm

Hello,

# cancel -a

this is really nice to erase an active task

i have this :



linux-opensuse131:~ # /usr/lib/cups/backend/lxhcp
linux-opensuse131:~ # systemctl stop SuSEfirewall2.service
linux-opensuse131:~ # /usr/lib/cups/backend/lxhcp


nothing is returned in console, see below the error log :

In the set up of the printer there’s allready an IP adress being used , i’m gonna try to use this in the lxtoolbox utility.
actually this toolbox is only usefull about cartridges, cleaning them for example , printing a test page also and adding a wifi connection to the printer.
(*edit : ok i was going to post this when i suddenly saw 3 windows popping up and allowing me to choose the IP , i guess there was a delay for i tried to add a new printer a bit before using the big + icon , i was then able to set the ip in the utility box menu)

can i leave DHCP On in the printer menu or is it better to turn it Off ? (it’s On now, i don’t want to disturb the behavior of the windows machine as it’s working ok)

Thanks

ps : adding the IP using DHCP finally allowed printing ! Notice that i never had to do so before i guess it’s the safer way , it looks like mac adress can be “lost” sometimes.

deano_ferrari · July 29, 2014, 8:44pm

Nothing returned from the running the backend essentially means that your printer was not discovered following the broadcast packet(s). The log doesn’t really tell me what was failing, and it would probably take some tcpdump analysis to get a better idea about what was wrong.

Yep, the delay results from an initial broadcast to get the printer to respond by MAC addressing.

Just be careful about having a dynamically-assigned IP address. Usually, it is possible to assign a static (fixed) address for printers. Many domestic routers, do hand out the same address to specific devices (identified by their MAC addresses), but not all. If the IP address changes for some reason, then you’ll have to adjust the URI in /etc/cups/printers.conf accordingly.

Anyway, I’m glad we finally got your printer working from your *nix box.
