bannertops does not work in general. This command line already leads to the reported problem:

/usr/lib/cups/filter/bannertops 1 1 1 1 "PageSize=A4" < /usr/share/cups/data/testprint > x

[Till Kamppeter (till-kamppeter)]

Looks like a problem in the original code of the bannertops filter. Submitted problem upstream:

http://www.cups.org/str.php?L3787

[Till Kamppeter (till-kamppeter)]

According to the CUPS upstream bug report

http://www.cups.org/str.php?L3787

this is a problem of libpng. Mike Sweet, the author of CUPS recommends filing an upstream bug in libpng, with the Valgrind results which are attched to the CUPS upstream bug.

[Till Kamppeter (till-kamppeter)]

Note that the offending PNG image is /usr/share/cups/doc-root/images/cups.png, an 8-bit-per-pixel colormap type image:

till@till:~/ubuntu/cups/bzr/build-area/cups-1.4.6$ file /usr/share/cups/doc-root/images/cups.png
/usr/share/cups/doc-root/images/cups.png: PNG image data, 128 x 128, 8-bit colormap, non-interlaced
till@till:~/ubuntu/cups/bzr/build-area/cups-1.4.6$

You get the same failure if you try to print the image by directly sending it to CUPS:

/usr/lib/cups/filter/imagetops 1 1 1 1 "PageSize=A4" /usr/share/cups/doc-root/images/cups.png > x

PNG images with 24/32-bit-per-pixel work correctly.

[Till Kamppeter (till-kamppeter)]

A workaround to be able to print the CUPS test page again is to convert /usr/share/cups/doc-root/images/cups.png to RGBA:

convert /usr/share/cups/doc-root/images/cups.png PNG32:cups.png
sudo cp cups.png /usr/share/cups/doc-root/images/

After that the test page prints again. But note that printing 8-bit-per-pixel PNG files directly to CUPS will not work. Those files you have to open with eog, shotwell, GIMP, or any other image application and then print out of the application.

[Till Kamppeter (till-kamppeter)]

Added CUPS task for the workaround. But note that this is not a fix. The problem in libpng needs to get fixed for Natty.

[Till Kamppeter (till-kamppeter)]

The CUPS package with the workaround will get uploaded after the release of beta 1 of Natty this Friday. If you need the problem solved urgently, follow the instructions in comment #7.

[Juan Pedro Paredes (juampe)]

OK, I verified the workaround in #7. It works fine for testing purposes.
Good job

Me install hp firmware for HP1006 and printer now....

This bug was fixed in the package cups - 1.4.6-4

---------------
cups (1.4.6-4) unstable; urgency=low

  * debian/patches/fix-broken-ipv6-uris.dpatch: When accessing the web
    interface via http: (unencrypted) and one does an adminstrative task
    which requires encryption, on upgrading to https: (encrypted) mode
    IPv6 IP addresses without "[...]" get inserted into the URL and the
    browser cannot parse the URL correctly. Fixed with a patch from upstream
    (LP: #744674).
  * debian/rules: Convert cups.png (CUPS logo for test page) to RGBA, as the
    original 8-bit-per-pixel color map format leads to a crash in libpng. This
    prevents the CUPS test page and the banner pages from printing
    (LP: #710881).
  * debian/control: Add ImageMagick to the build dependencies, as it is
    needed for the CUPS logo image conversion.

[Till Kamppeter (till-kamppeter)]

I have found a build problem. The fix works well with a package which I build on my local machine, but with a package built on buildds it fails.

So I get the following (having a locally rebuilt binary package of "cups", using 1.4.6-5 in all cases):

till@till:~/ubuntu/cups/bzr/debian-trunk$ sudo dpkg -i cups_1.4.6-5_amd64.deb
...
till@till:~/ubuntu/cups/bzr/debian-trunk$ file /usr/share/cups/doc-root/images/cups.png
/usr/share/cups/doc-root/images/cups.png: PNG image data, 128 x 128, 8-bit/color RGBA, non-interlaced
till@till:~/ubuntu/cups/bzr/debian-trunk$ sudo apt-get install --reinstall cups
...
till@till:~/ubuntu/cups/bzr/debian-trunk$ file /usr/share/cups/doc-root/images/cups.png
/usr/share/cups/doc-root/images/cups.png: PNG image data, 128 x 128, 8-bit colormap, non-interlaced
till@till:~/ubuntu/cups/bzr/debian-trunk$

So cups.png has the correct format with the locally built package but the wrong format with the package built by buildds.

The conversion is done in the debian/rules file, in the "binary-post-install/cups::" rule, by running the command line

convert debian/$(cdbs_curpkg)/usr/share/cups/doc-root/images/cups.png PNG32:cups.png && \
        mv -f cups.png debian/$(cdbs_curpkg)/usr/share/cups/doc-root/images/

How has this to be done correctly so that buildds produces the correct files.

pitti, can you help here? Thanks.

[Martin Pitt (pitti)]

I really doubt it's a huge libpng problem, as these images work correctly everywhere else (eog, firefox, etc.). Thus I close the natty task and just keep the general task.

[Launchpad Janitor (janitor)]

This bug was fixed in the package cups - 1.4.6-5ubuntu1

---------------
cups (1.4.6-5ubuntu1) natty; urgency=low

  * Revert calling "convert" on the banner PNGs (r961); the file is already
    correct in the source. The format conversion happens in Ubuntu's
    pkgbinarymangler, so it does not affect Debian builds at all and also this
    cannot be circumvented that way. Instead, blacklist this package from
    pkgstripfiles. (LP: #710881)

pitti, thanks for the quick fix.

[Till Kamppeter (till-kamppeter)]

pitti, your fix works, buildds has kept the PNGs in the correct format now.
