Cups on MyBook WE White Light, a torture

Cups on MyBook WE White Light, a torture

berwinter 1252317720|%e %b %Y, %H:%M %Z|agohover

Hi,

I have tried for a long time to run cups on my WD MyBook World Ed (white light), but it won't work!
Yesterday I managed to compile the usblp.ko module on my Ubuntu Box and copied it to my MBWE. (The module usblp, I think, is needed for the linux printing support, right?)

After loading the module I have some new devices in /dev/

/dev/usblp0

/dev/usb/lp0
/dev/usb/lp1
.
.
/dev/usb/lp7

and lsusb say:

Bus 001 Device 003: ID 04f9:0027 Brother Industries, Ltd

If I send some ASCII Code to the printer-device (echo Hallo > /dev/usblp0), the printer makes only some noises but doesn't print anything. I think this is because my printer (Brother HL-2030) doesn't support direkt ASCII printing.

I also set the device-permission to user root and group lp and changed the cupsd.conf

4 -rw-r--r-- 1 root lp          6 Sep  7 11:46 usblp0

But cups won't find my printer in the web interface!

What else can I try?

Thanky,
bertram

Hey I am about to look into CÚPS on a white light soon. Did you just use the blue ring guide to install it? If/when following the bluering guide should you do anything different when it is a white light?

You should load the usb filesystem….
If you are actively using the whitelight as a linux system, you should really do some modifications to it…

All modification which I think are necessary are taken care of with this script:

wget -O prep_whitelight http://wd.mirmana.com/prep_whitelight
sh prep_whitelight

Part of it is a script which loads the usbfs which is necessary for some usb-programs. I do believe it's deprecated….

First you need the prep_whitelight script as frater said for the necessary basic setup and to setup optware. Then you can install cups:

/opt/bin/ipkg install cups
/opt/bin/ipkg install cups-pdf
/opt/bin/ipkg install cups-doc
/opt/bin/ipkg install cups-driver-gutenprint

I think on the whitelight you don't need to recompile cups as it is descripted in de bluering-guide.
Configure the cupsd.conf file like in the bluering-guide.

If you also need the usblp.ko module for Kernel printing support you could compile it from the Western Digital Sources or I would send it you.

Hi,
I have the same problem, I also ran the prep_whitelight script but it did not help recognizing my Brother printer in the cups webinterface. I would really appreciate a description of scripts and steps after which cups runs properly on an untouched whitelight and recognizes e.g. a Brother printer HL-XXXX.

hey,
I just managed to print with my Brother HL2030 on the MyBook (whitelight). If required I would publish a Totorial/HowTo in the next days or weeks.

The Google Translate version of your page is not bad at all: Google Translate

Unfortunately, I got a problem while applying prep_whitelight, so I couldn't follow the steps, but I'll be back!
Great job!

Which error did you get while running prep_whiteight?

There was a temporary problem after installing the new wget version. More details here: http://mybookworld.wikidot.com/forum/t-184528/prep-whitelight-wget-breaks-after-update-from-optware

Hello berwinter,

I followed your tutorial and managed to get my HP printer working. Thank you very much - your kernel module was the missing link.

You can add the following information to your tutorial:
- instead of editing the printers file, you can add your printer using the web interface - the printer is detected as being connected to LPT1 (even if it's USB).
- the CUPS on the MBWE can't print test pages - It says everything is ok, but the printer never prints anything. If you generate a test page from the computer (through the network), the printer works. So, there's no need to worry about the test page not working.

Anyway, good job!

Re: Cups on MyBook WE White Light, a torture

berwinter 1253895852|%e %b %Y, %H:%M %Z|agohover

thanks for the feedback!

I will update the tutorial with your information.

Yes cups can't print test-pages on the mybook. This is because in my tutorial I used raw printing, so cups has no print-driver and can't generate the testpages. Maybe it would work if you use the ppd driver…

greetings

Hi berwinter,

thanks for your tutorial, but now I am stucked a bit.

I did everything as you said in your tutorial, but my HL-1430 still refuses to print.

lsusb says:

Bus 001 Device 002: ID 04f9:001a Brother Industries, Ltd HL-1430 Laser Printer
Bus 001 Device 001: ID 0000:0000

I can also try "echo Hi > /dev/lp0" and the yellow light on the printer flashes, but nothing else happens.

I tried to search for a new printer in CUPS, but it's not found.

Then I tried to add it by myself, but I can't select the parallel port in the add printer dialog. So I chose the serial port and modified the printers.conf manually afterwards. But this all won't get the printer started. Instead I have an error in CUPS saying "Filter "foomatic-rip" for printer "1430" not available: No such file or directory".

Do you have any suggestions?

PS: When I use your starting script it says "lp: no such group" - so I changed the lines from "sys:lp" to "sys:sys"

EDIT: I now did a "chmod 777 /dev/lp0" and now my printer is printing with the settings given in your tutorial. But 777 isn't nice, though…

maybe you have to add the group lp manually by using the addgroup function or change also the group in /opt/etc/cups/cupsd.conf to sys.

The problem with "echo something > /dev/lp0" is that there is no driver for the printer on the mybook which translate the text into raw for the printer.

Thank you for your great Tutorial, but i've meet a dead end, and i hope you guys can help me:

I followed your Tutorial, and it worked great till the start of the Init Script, i always get the following error:

[root@MyBookWorld dev]# /opt/etc/init.d/S88cupsd start
BusyBox v1.1.1 (2008.11.20-08:20+0000) multi-call binary

Usage: insmod [OPTION]... MODULE [symbol=value]...

/opt/etc/init.d/S88cupsd: line 14: /lib/modules/2.6.24.4/kernel/drivers/usb/class/usblp.ko: Permission denied

I've ignored this and added a printer, but the time i like to print all i get is a error from CUPS:
"Unable to open device file "/dev/lp0": No such device"

I've checked this in the shell, dev/lp0 isn't a device, but i cant find my failure, I bet i've missed the important little part, but i can't tell which part this is.

Sorry, for my bad english, i speak german as my native language.

edit: the printer is also listed by lsusb?! What went wrong?

Maybe there is a problem with insmod. Try to load usblp.ko manuell:

insmod /lib/modules/2.6.24.4/kernel/drivers/usb/class/usblp.ko

Please also check if there is the usblp.ko file in the right directory and has the right permissions.

KRID221993 1255527738|%e %b %Y, %H:%M %Z|agohover

Found my failure, after trying to load manually i've seen, that in the start script was a line break after the insmod, probably nano, probably me(greater chance i say :-) ), so after removing it all worked.
Thanks for your fast help and the Tutorial!

This post is great, the guide of berwinter's really helped. One thing I had to do in addition to the guide was use the 'addgroup' function to create an 'lp' group, otherwise the startup script would fail.

Another piece of feedback:

After creating my printer, I noticed that it defaults to being "Stopped", so whenever my MBWE reboots, I have to remember to go to the CUPS admin page and "Start" the printer. I found a solution in a post by frederikk, so I added a couple lines to my _SK88cupsd file AFTER completing the initial setup and creating my printer. The lines simply sleep for 10 seconds after starting up cups, then start the printer. My _SK88cupsd file now looks like this:

#!/bin/sh 
  # 
  # 
  # 
  case "$1" in 
          start) 
                  if ( [ ! -c /dev/lp0 ] ) then 
                          mknod /dev/lp0 c 180 0 
                  fi 
                  /bin/chown sys:lp /dev/lp0 

                  if ( !(lsmod | grep "^usblp" -q) ); then 
                           insmod /lib/modules/2.6.24.4/kernel/drivers/usb/class/usblp.ko 
                  fi 

                  if [ -n "`pidof cupsd`" ]; then 
                          /usr/bin/killall cupsd 2>/dev/null 
                  fi 
                  /opt/sbin/cupsd
                  sleep 10
                  /opt/sbin/cupsenable HP-Deskjet-812c
          ;; 
          stop) 
                  if [ -n "`pidof cupsd`" ]; then 
                          /usr/bin/killall cupsd 2>/dev/null 
                  fi 
          ;; 
          *) 
                  echo "Usage: (start|stop)" 
                  exit 1 
  esac

Hello, and first of all thanks for the tutorial.

I'm configurating cups to do step by step this tutorial. My problem comes when I try to execute /opt/etc/init.d/S88cupsd start
The error says:
cupsd: Child exited with status 1!
I changed intervals IP, 192.168.1.0
I supose that my cups.conf file have a error because if launch cupsd with -c cups.conf.old its works.
What is wrong?

Thks

Hi!
I posted cups files in this link with html format. I hope your reading easier.
If you need other files, tell me

Thanks again

Maybe you only need to change the line 834 from:

Require @SYSTEM

to:

Require user @SYSTEM

Hello, I have been working on this as well, and thanks to the posts in this thread and berwinter's guide, I have gotten close to completing this

EDIT: nvm what this post was, I have it set up now but am only having issues with the print jobs going through. I have the printer added on the CUPS web interface and on my PC, but jobs just sit on my PC and don't show up in the web ui. I think it'll just take more tinkering with.
