Bugzilla Bug 156262

When I try to print something after the update of cups I get a message similar
to this: "Depending printing process could not be started: [...]"
When I try to execute the shown command I get: "This utility doesn't support
printing from STDIN"
I was able to strip this down to a commandline like this: "cupsdoprint -P
'MYPRINTER'"
Where MYPRINTER is the name of my printer.

Please try to rebuild kdelibs and tell me if it works after that. If not,
please reopen.

*** Bug 156344 has been marked as a duplicate of this bug. ***

It doesn't work. Still the same problem. KDE tries to start cupsdoprint. When I
start it manually I am still told that it doesn't support printing from
stdin...

Should I perhaps also rebuild kdeprint???
Does anyone know why this bug suddenly happened?
Downgrading cups didn't help either... Is this a bug in the Gentoo patches to
KDE?

Dennis Schridde: I have tried rebuilding both cups and kdeprint with no
success. Well, we might at least compere each others printer related programs
versions; these are mine:

kde-base/kdelibs-3.5.5-r7 (my tip for a culprit)
kde-base/kdeprint-3.5.5
net-print/cups-1.2.7

Btw adding filename as the last parameter to the cupsdoprint command works well
for manual printing.

Problem persists, no fix found till now.

I am just glad that I didn't have to print something other than PDFs till now
(do it via acroread). Otherwise I would have been screwed.

That's the reason why I increased the severity to major. (You could even see it
as critical, IMO, because it makes all and every KDE application completely
unable to print.)

I am using the same versions:
kde-base/kdelibs-3.5.5-r7
kde-base/kdeprint-3.5.5
net-print/cups-1.2.7

Same here, cups 1.2.6, kde 3.5.5 and kdelibs recompiled - still not able to
print with kde.

Is there actually a maintainer of this bug? Is there even a Gentoo-Printing
team? It seems as if no one cares about this problem... :(
Perhaps the assignment should be switched to some other group? KDE maintainers
maybe? (Other programs, like AcroRead, GIMP and similar do not have this
problem.)

I tried downgrading kdelibs, cups and kdeprint to a previous version. There
were some bockers with kdeprint (3.5.2) therefore I downgraded only kdelibs (to
3.5.5-r6) and cups (to 1.2.6). I rebooted and printing worked again. Then I
emerged previously quickpackaged kdelibs-3.5.5-r7, restarted both kde and cupsd
and printing still worked.

I am currently re-emerging kdelibs-3.5.5-r7, cups-1.2.6 and kdeprint-3.5.5 from
sources to see if downgrading cups was the real solution.

Well, downgrading cups to version 1.3.6 solved this bug for me.

Downgrading to 1.3.6? I guess you mean 1.2.6?
Well, for most of us this didn't help...

You are right, I meant 1.2.6.

I remember kdelibs and cups were the last packages I emerged before the problem
occured. Kdelibs r6 and r7 AFAIK differ only in some xinerama patches therefore
cups should be the culprit.

I admit not to understand "the magic behind" but I will provide any information
you need. In fact I did nothing more than emerging older cups and re-emerging
kdelibs.

It seems I have the same problem here. I can't .print pdfs nor send them to
fax. But a standard text-file I can print without any problem. With acroread I
can print .pdfs as well. So it seems the problem is in the format-changing
(from .pdf to .ps I think). I already have recompiled xpdf, cups, kdelibs and
kdeprint -- with no success.

Here my versions:
kdelibs-3.5.5-r5
kdeprint-3.5.5
cups-1.2.6
xpdf-3.01-r8

i can confirm problem exists with cups-1.2.6 and kdelibs-3.5.5-r5

problem does _not_ exist with cups-1.1.23-r8 and kdelibs-3.5.5-r5

i recompiled kdelibs after downgrading cups but dunno if it's necessary.

at least now my users can print from kde apps.

I just tried like you said:
Downgrade to cups 1.2.6 and reemerge kdelibs.
Result: Same as before... Still no printing in KDE. :(

I admit I have no idea what is it going on. I wanted to test the issue a bit
further and therefore did "emerge =cups-1.2.7 && emerge kdelibs kdeprint". I
hoped printing will NOT work. I rebooted pc, started kde, started cupsd and
printing works.

I have found out that 'emerge =cups-1.2.7 && emerge kdelibs kdeprint' and pc
restarted really disables my kde printing while 'emerge =cups-1.2.6 && emerge
kdelibs kdeprint' eneables kde printing. I have tested it twice recently.

The working cups 1.2.7 was probably caused by me not restarting cupsd. Sorry
for such hoax :-(

I have masked 1.2.7 a while ago, without that it would have fixed the problem.
I just have updated to KDE 3.5.6 and the problem still persists...

I still have no idea how to enable printing on my machine.

With 
 cups-1.2.6
 kde-base/kdebase-3.5.5-r3
--> printing does not work

Then i went back to
  cups-1.1.23-r8
recompiled kdebase and printing is still not working.

I dont have kde-print explicitly installed, but as printing worked before the
update to kde-3.5.5, i guess this is somehow part of kdebase (it is also not
possible to emerge kde-printing when kde-base is installed).

Print magically works again here (since a while).
kdelibs-3.5.6-r5
kdeprint-3.5.6
cups-1.2.10

This bug got fixed upstream. it worksforme and I am on KDE: 3.5.7
