Then why does it print with Windows XP on the Laptop?
I tried every USB-Port i have.. this messages apparently doesn't appear every time...

But still nothing. At the moment, the job doesn't even appear in kjobviewer. |

YEEEEEAAAAAHH!
Okay. I tried it with the old version again.
/etc/init.d/cupsd stop; emerge -C cups; rm -R /etc/cups;
masked 1.2, and emerged cups
Reinstalled the printer with "splix" drivers. Then got a errormessage about ghostscript-esp, reemerged ghostscript-esp, and it's printing.....
finally....
Nonetheless, thank you all very much for your time and effort. Such things are making me crazy. |

404 is "File or directory not found": the line or lines in the access_log as well as error_log could be helpful.
[Edit] this post says that a 404 problem was solved by copying cupsd.conf.default to cupsd.conf |
Well, in access_log it is just
| Code: |
localhost - - [23/Nov/2006:23:06:02 -0700] "GET / HTTP/1.1" 404 0 - -
localhost - - [23/Nov/2006:23:06:02 -0700] "GET /cups.css HTTP/1.1" 404 0 - -
|
and in error_log
| Code: |
D [23/Nov/2006:23:06:02 -0700] cupsdAcceptClient: 6 from localhost:631 (IPv4)
D [23/Nov/2006:23:06:02 -0700] cupsdReadClient: 6 GET /cups.css HTTP/1.1

...
D [23/Nov/2006:23:06:02 -0700] cupsdAuthorize: No authentication data provided.
D [23/Nov/2006:23:06:02 -0700] cupsdSendError: 6 code=404 (Not Found)
D [23/Nov/2006:23:06:02 -0700] cupsdCloseClient: 6
|
I know that playing with cups config solves it. I thought I did it a week ago. I obviously was able to go to localhost:631, manipulate printers, print test page.
And (seemingly) changing nothing week later got 404 again. |

This seems valuable information: it can't access the DocumentRoot directory nor can it access the file cups.css in it.
The Documentation via http://localhost:631 (1.2.7) says that the default DocumentRoot is /usr/share/doc/cups but the ebuild sets --with-docdir=/usr/share/cups/html.
Here the permissions on /usr/share/cups/html, /usr/share/cups/html/index.html and /usr/share/cups/html/cups.css are | Code: | $ ls -l /usr/share/cups/html
total 68
drwxr-xr-x 11 root root 4096 Nov 18 11:11 ./
drwxr-xr-x 11 root root 4096 Sep 10 08:52 ../

Would you like to check your permissions?

Thanks for the hint, I was not explicitly aware where the DocumentRoot is.
My permissions are fine, and I just made localhost:631 to work, but have no idea how. My cups conf file is from 1.1.x version while I'm currently running 1.2
I knew there have been changes, but I did not want to blindly copy new cupsd.conf.default since I had some custom stuff (+ 1.1 ersion had many more usefull comments).
So I have incorporated new changes seemingly everywhere.
I can swear, this time the following combination of commands made localhost:631 reply
Start with non-working state
| Code: |
cp cupsd.conf cupsd.conf.my
cp cupsd.conf.default cupsd.conf
/etc/init.d/cupsd restart
|
It works ! And then
| Code: |
cp cupsd.conf.my cupsd.conf
/etc/init.d/cupsd restart
|
And it still works !!
So I bit a bullet, took cupsd.conf.default , spent the last hour introducing there all my custom stuff, and it currently works.
There is something pretty tricky with authentication and access permissions and I learnt nothing.
I used to laugh at our administrator who was always complaining that with CUPS you are never certain will it work or not,
but must admit that with 2 years of cups, I did not get this certainty either. |

I used to use lpd and with that I had to have parport, parport_pc and lp as modules, rmmod them, switch on the printer, modprobe them and then (usually) it worked.
When I started using CUPS I was amazed that I could simply switch on the printer and print. I can't say I've had many problems but these forums are living proof that this doesn't apply to all

There are many useful features that CUPS have, and printer automatic discovery and queue setup is one of them, especially valuable with laptop in unknown environment.
However there is something inherently flimsy to CUPS configuration. You know, there is no robustness.
I'm in university environment and you never now what list of printers you will see today. I'm like other profs managing my own computers and printers (department manages the students and general purpose ones) and I bet few of my colleagues know how to limit the broadcast, or what you are listening to (BrowseAddress and BrowseAllow options are not that intuitive and obviously misnamed), and sometimes I was seeing printers across the campus, with my own printers hidden on the third page, default printers were changing all the time, etc.
Now I seem to get a stable setup - but essentially at the cost that I had to manually define accesses to a specific computers and printers. Not much different of what I had to do with lpd.
One the other hand, use of PPD's and printer capabilities is a nice stuff, of course. |

CUPS is a complex system, it only appears simple to set up because of the work done on the web administration.
This apparent simplicity hides the real complexity, that is, you don't really understand what you are doing and mistakes are made.
And, like all complex systems, once you need to go past the everyday, it's an uphill struggle and requires time and effort and understanding.
If this time and effort isn't part of your paid job and doesn't contribute to "What have you done for me today?" it becomes next to impossible.
Thus the anguished cries. Particularly when term papers are due in tomorrow...

When I did the cups 1.2 upgrade, I took the advice that the ebuild offered:
| Code: | WARN: postinst
The configuration changed with cups-1.2, you may want to save the old
one and start from scratch:
# mv /etc/cups /etc/cups.orig; emerge -va1 cups
You need to rebuild kdelibs for kdeprinter to work with cups-1.2
/usr/lib/cups exists - You need to remerge every ebuild that
installed into /usr/lib/cups and /etc/cups, qfile is in portage-utils:
# FEATURES=-collision-protect emerge -va1 $(qfile -qC /usr/lib/cups /etc/cups | sed "s:net-print/cup
s$::")
FEATURES=-collision-protect is needed to overwrite the compatibility
symlinks installed by this package, it wont be needed on later merges.
You should also run revdep-rebuild
|
I just reconfigured cups starting with the defaults. About the only thing that had me going was that the default mimes.conv file had the following comented out:
| Code: |
application/octet-stream application/vnd.cups-raw 0 -
|
...which brokes printing from other machines using samba (if you use the the samba default which uses raw printing to cups).

I had the same issue on a server. After playing around some time (including dozens of kills / zaps) it somehow started to work again. Unfortunatelly I can't recall exactly how, but I am trying the same thing on my home machine now.

I had the same problem saying the connection was lost.
I even reinstalled cups and the foomatic packages without any success.
Then I deleted my printer and simply reinstalled it, and everything work again.

Reinstalling everything and installing the OLD version fixed my issue particially: I can print on the local machine. But accessing cups over the network does not work even after 10 hours of troubleshooting  I got the message "the printer is busy". I reinstalled on both machines, server and client, and i used the same Printer URL like before - I am giving up
