Topic: CUPs seems to work but i can't install the printer (missing libxml)

[jcc]

Hi.
First thanks for that great distribution of SME server.
No compare to everything i tried before (e.g. ubuntu- and debian-server).

Because the default-printer-component (LRP?) did not work with my printer, I installed CUPS.
It seems to work (I logged in the web-frontend) but i can't install my printer: a Canon pixma iP4000.

I tried it this way: download of
ftp://download.canon.jp/pub/driver/bj/linux/bjfilter-common-3.50-2.i386.rpm
ftp://download.canon.jp/pub/driver/bj/linux/bjfilter-pixusip4100-lprng-2.50-2.i386.rpm
ftp://download.canon.jp/pub/driver/bj/linux/bjfilter-pixusip4100-2.50-2.i386.rpm

But when i try

Code: [Select]

yum localinstall bjfilter-common-2.50-3.i386.rpm
i get this

Code: [Select]

Error: Missing Dependency: libxml is needed by package bjfilter-common

What do i have to install too?

Another bug: When i click the "printer"-link in the sme-server-web-frontend i get this error:

Code: [Select]

Internal Server Error

The server encountered an internal error or misconfiguration and was unable to complete your request.

Please contact the server administrator, admin and inform them of the time the error occurred, and anything you might have done that may have caused the error.

I´m not sure if you follow this: http://wiki.contribs.org/Cups

If you don´t... you should

Step back your steps and follow the wiki.

Thanks

Installing CUPS will not benefit you, assuming you are using Windows workstations.

You do not install printer drivers onto sme server.
In a typical Windows workstation environment you install the printer driver onto each Windows workstation.
The standard lprng raw printing should work OK for most printers, except those that require bidirectional "talk" with Windows, or those that use some of the processor power in your Windows workstation.

You need to use "standalone" type printers.

Not really 100% right... if you have a winprinter MAY have a way to do they work using foomatics and CUPS.

You do not install printer drivers onto sme server.

again, not 100% right... you CAN install printer drivers on sme server and have them deployed on windows computer when you connect to printer: http://wiki.contribs.org/Printer_Drivers_for_Windows_Workstations

In a typical Windows workstation environment you install the printer driver onto each Windows workstation.

in a typical Windwos workstation environment using raw printing you install the printer driver on each windows workstation. When using server side processing (something CUPS is capable of!) you can install a generic PS driver in each computer with a printer name as "Financial Printer" and user will not care about what printer is on financial depto, just will get they job there! If you change printer, all you need to do is update server side configuration (on CUPS) to process the request. It´s A LOT of work... or not!

You need to use "standalone" type printers.

That´s not you only option... just easier one.

Your answers clarifying and qualifying are valuable.

My answers were given in the context of the original posters (OP) question and my reading/interpretation of OPs issues.

OP was trying to install Canon linux drivers directly to sme server which did NOT appear to be appropriate in the OP's situation, assuming OP was using Windows workstations (and using raw printing), which seemed a reasonable assumption as OP did try the standard sme printing system first.

OP also did not appear to be talking about deploying printer drivers from sme (which is not a typical or standard configuration).

As OP seemed unsure of printing concepts, I was keeping answers at a basic level.

Your answers are for an advanced user with specific needs and requirements, and may well be "an answer" if OP wants to pursue advanced configuration.

I'm sorry... I did not want to offend you.
I'm sorry if I got too technical. I was just registering options for someone else who may search the forum in future.

Sorry! :$

Hi.

i deleted my just written posting, because i forget the verification...

So one more time but now much more shorter:
   
I removed cups and (re-)installed LPrng.
I added my printer via 1st usb. (i could not found the "standalone"-option)

Code: [Select]

usb 2-3: new full speed USB device using address 5
drivers/usb/class/usblp.c: usblp0: USB Bidirectional printer dev 5 if 0 alt 0 proto 2 vid 0x04A9 pid 0x1093
[root@server ~]#

I found the printer in the network and installed the driver on my windows-notebook.

Now i can send printing-jobs but the printer still does nothing.

In the server-manager adress and remotename are N/A. I think this is ok for a local printer.

Where can i screw?

Sorry, I couldn't resist answering this, although I guess there is a language issue here.

Where can i screw?

Anywhere the mood takes you !

[jcc]

Hmmm,
sorry i translated this 1:1 from german.

Seems to have another meaning in english...

Those should be OK. Have you plugged the printer into USB1 on the server ?
It might also be worth restarting the server, while the printer power is on.

i could not found the "standalone"-option

It's not an option, it is just a generic term for a type of printer that is not dependent on any operating system or requiring support from the computer processor eg commonly called a Winprinter as it requires processing power from a computer running a Windows OS, or a printer requiring bidirectional talk between workstations and printer in order for all functions to operate eg multi function printers/devices.

Code: [Select]

usb 2-3: new full speed USB device using address 5
drivers/usb/class/usblp.c: usblp0: USB Bidirectional printer dev 5 if 0 alt 0 proto 2 vid 0x04A9 pid 0x1093
[root@server ~]#

What is that code you are quoting, when and where do you see that ?

I found the printer in the network and installed the driver on my windows-notebook.

When you setup the printer in server manager, you would have given it a name eg pixma4000. So you should point your Windows printer driver port at that network printer share name ie //server/pixma4000 (or whatever your server and printer names are).

To test that your printer driver is installed correctly on your Windows workstation and that it is talking to your printer correctly, please connect the printer directly to a USB port on your workstation, configuring the printer driver for the correct USB port as necessary. This should prove if it all works OK before connecting the printer to the server.

I just cannot work out what this should have translated to, but I hope it has been answered by the above answers/suggestions.

[jcc]

Yes. First i did not found the printer in dmesg, so i switched it off/on and then i found that code in dmesg.

It's not an option, it is just a generic term for a type of printer that is not dependent on any operating system or requiring support from the computer processor eg commonly called a Winprinter as it requires processing power from a computer running a Windows OS, or a printer requiring bidirectional talk between workstations and printer in order for all functions to operate eg multi function printers/devices.

Ok. You saw that it is a bidirectional printer, but i do not need the bidirectional features.
Once I used a debian-server the printer worked as a networkprinter , but i used cups.

I just wrote above.

I did. Locally connected everything worked fine.


If you have a real complicated and complex system, you describe all the switches and possibilities as "screws", that you can screw up in the one or other direction.
But i think it won't improve my situation., so i better stop writing about "screwing"...

OK that suggests the Windows printer driver is the correct driver, and that it is installed correctly and that the printer does work.

Therefore something is wrong with how the Windows workstation is talking to the printer via the sme server. As sme passes raw data to the printer then it is not changing the data sent to the printer in any way, so it's a puzzle then.

It may well be that the printer itself requires bidirectional information in order to function correctly. You best check with the printer manufacturer/specifications etc.
If you required CUPS on another Linux system when using that printer then maybe that will also be required on sme.

Have you tried another printer to ensure your whole setup is valid ?

You could try installing the print queue monitor to see if jobs sent from the printer actually get queued, but I think doing that will only be of diagnostic value at this time.
http://wiki.contribs.org/LPRng_print_queue_monitor

It sounds to me that the problem is with your printer, and as such it may require advanced configuration on sme, if it is possible to get it working.

[jcc]

Hi Mary,
i installed the print queue.
the printer pixma is shown, but when i choose the printer to watch the queue, the plugin says "Not a LPRng print queue - no admin commands available".


For sure i tried "Print Test Page" but the printjob is wether shown in the queue nor printed...


In the logs i could not find anything that could help.

[Jáder]

jcc,
Please tell us what is your brand and model printer. (eg. HP 2035N).
I' suspecting you're triyng to use a winprinter on SME raw mode.
If it's a Canon Pixma 4000 it works on linux, but I suspect just using CUPS (see link above): http://openprinting.org/show_printer.cgi?recnum=Canon-PIXMA_iP4000
