Make a simple small web site describing your program with the source 
tarball for download (give a free software license, like GPL or MIT to 
your code).

If you want to package it for Ubuntu, see the developer part of the 
Debian web site for instructions how to make .deb packages. Use the PPA 
(Personal Package Area) on Lauchpad to make your package downloadable 
and auto-updateable.

How do you make a dialog popping up triggered by CUPS executing a print 
job? DBUS?

Do you take into account that cupsys was renamed to cups in the Intrepid 
release cycle? This means the figures of "cupsys" and "cups" bugs have 
to get summed up. For triagers it menas that everything which is still 
valid in Intrepid needs to be moved to "cups".

In addition. triagers should know that the printing subsystem consists 
of many packages, not only cups, but also ghostscript, foomatic-*, 
hplip, gutenprint, splix, system-config-printer, ... Users do not know 
that and assign printing-related bug reports to cups/cupsys or 
system-config-printer in most cases. Triagers should move these to the 
correct packages.

The best would be to add support for package renaming to Launchpad: 
Package pages should show the full history, also of the releases under 
old names. Going to the URL of the old name should automatically forward 
the user to the new name. Same for bug reporting. New bugs reported for 
a renamed package should be automatically posted under the new package 
name and existing bugs be moved.

I would say you move all bugs to cups by a script and then regenerate 
the list.

Deprecating X screen display by Ghostscript

[Till Kamppeter]

Hi,

recently, many bugs got reported to Ghostscript upstream that certain 
files do not display on the screen with Ghostscript, with Ghostscript 
erroring out on them (links for example bugs below). It turned out that 
the "x11alpha" output driver of Ghostscript is the culprit. This is the 
antialiased X-Window output device of Ghostscript which is used by every 
desktop program which displays PostScript files on the screen, perhaps 
even by one or another program which displays PDF files, as Ghostscript 
is also a PDF interpreter.

I talked with the Ghostscript upstream developers about this problem and 
they recommended me to not use the X output devices of Ghostscript any 
more, as they do not only have these bugs but also do not allow to 
search text in the displayed file. PDF should be displayed with Poppler 
and PostScript be converted to PDF using the "pdfwrite" output driver of 
Ghostscript and then also displayed with Poppler.

This would also simplify the screen display applications as the 
displaying is done only by Poppler and not sometimes by Ghostscript and 
sometimes by Poppler.

Can everyone who is maintaining a PostScript screen display utility 
(evince, okular, ...) look into doing PostScript display as described? 
If it would be possible for Maverick it would be great, but at least 
reporting the problem to the upstream developers would be nice. If it is 
not possible for Maverick, we should at least change the Ghostscript 
calls not to use "x11alpha" but the simple "x11" output device. This way 
we can surround the bugs at least.

Desktop CDs: Around 60 MB saved on the installed system, 28 MB in binary packages

[Till Kamppeter]

Hi,

the Google Summer of Code 2010 is over and the only student working for 
OpenPrinting, Vitor Baptista from Brazil, was successful with the 
project of effectively compressing PPDs for PostScript printers which 
are physically residing on the system. I have made use of this software 
now in the foomatic-db and hplip packages leading to the following savings:

Binary Package *.deb file   installed system

openprinting-ppds   ~4 MB  ~5 MB
openprinting-ppds-extra~18 MB ~28 MB
hplip-data  ~4 MB ~26 MB

So on the running system of the Desktop CD 31 MB get saved which can be 
used for other useful things.

All these savings are solely reached by lossless data compression. No 
functionality is removed from the PPDs, not even comments. Especially 
the multi-language support of HP's PPDs is conserved.

Note also that the splitting of openprinting-ppds and 
openprinting-ppds-extra was done to remove a big part of the 
space-consuming PPD files from the Desktop CD. Now as the data is vastly 
compressed I am thinking about merging the PPDs of 
openprinting-ppds-extra back into openprinting-ppds and doing away with 
openprinting-ppds-extra. WDYT?

Why does it add 15 MB? openprinting-ppds-extra is also compressed: The

And I have freed another 2.3 MB (60 KB of .debs) in the installed

The space occupation of the PPDs I have already solved in Maverick. Most 
of the PPDs in /usr/share/ppd and also the Foomatic XML data in 
/usr/share/foomatic are replaced by highly compressed PPD file archives 
based on LZMA (in /usr/lib/cups/driver). This saves around 30-40 MB on 
the live system even getting the PPDs of the former 
openprinting-ppds-extra package onto the live CD. The tools for building 
these archives are from a Google Summer of Code project which I have 
mentored for OpenPrinting. See

https://bugs.launchpad.net/bugs/493282

and

http://pypi.python.org/pypi/pyppd

The packages on the CD which have their PPDs compressed now are: 
foomatic-db, openprinting-ppds, hplip-data, splix

URGENT: CUPS test page does not print due to buildds problem

[Till Kamppeter]

Hi,

it is about bug 710881, https://bugs.launchpad.net/bugs/710881. The 
workaround described in the bug report and applied to the CUPS package 
principally works but there is a problem with buildds. A CUPS package 
built on my local machine has cups.png correctly converted, but in the 
package built by buildds the cups.png file is not converted. See my last 
comment in the bug report.


Are PNG files in a Debian package generally converted to make them 
smaller (and this converts cups.png back to the bad format)?


Or does "convert" on the buildds behave different than "convert" on a 
local Ubuntu desktop box?


Or is there some problem with the subpackages for architecture-dependent 
and -indpendent binary packages being built in different buildds runs?


Or does the command line for the conversion error out but not stop the 
build (I did not see anything indicating this in the amd64 buildlog on 
the buildds servers)?


The conversion of cups.png is done in the "binary-post-install/cups::" 
rule  in debian/rules, by 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/


Any idea?

Please test AirPrint on Natty and Oneiric

[Till Kamppeter]

Hi,

as a first step into support for printing from mobile devices I have 
made Apple's AirPrint working on Natty and Oneiric. AirPrint is the 
method how Apple's iPhone, iPad, and iPod Touch print via IPP. I want to 
ask all of you to test this feature.



What do you need?
-

1. An iPhone, iPad, or iPod Touch with iOS 4.2 or newer. Update your 
device via iTunes if needed. If no update gets offered to you, update 
iTunes first, if after that you do not get an update offered, your 
device is too old.


2. A computer running Ubuntu Natty or Oneiric. Please update your 
computer to the newest state of the art with the update-manager.


3. A print queue on your computer. If you do not have a printer, create 
a pseudo printer with the following commands in a terminal:


cupsctl FileDevice=yes
lpadmin -p test -E -v file:/tmp/test.ps -m drv:///sample.drv/generic.ppd 
-o PageSize=A4


When printing on this printer, you get a PostScript file /tmp/test.ps. 
Make it world-readable and display it with evince.


4. WLAN. Switch the internet access of your mobile device to WLAN. Your 
computer must be in the same LAN (on the same router), but it does not 
matter whether it is connected via ethernet cable or WLAN.



How do you test?


1. On your computer start system-config-printer via System -> 
Administration -> Printing (GNOME Classic) or via Turn-off-button at the 
upper right -> System Settings -> Hardware -> Printing (Unity Natty) or 
via the command line (all systems including Unity Oneiric).


2. In system-config-printer choose Server -> Settings and activate 
"Published shared printers connected to this system". Click OK and then 
right-click on the icon of your print queue and choose Properties in the 
pop-up menu. In the Policies section of the dialog make sure that 
"Shared" is activated.


3. Make sure your mobile device is accessing your local network using 
WLAN and then open an application with printing functionality on it 
(like for example the browser or the photo viewer). Print something. The 
print dialog should show your print queue and allow some basic settings. 
Note that the Description/Info field and not the name of the queue is shown.


4. Check whether you get a correct printout.

The only way out was to use the 'Raising Skinny Elephants Is Utterly

I then downloaded the install script from HP and tried that.
In the first instance, I had to manually satisfy the dependencies, as
11.10 is not included in the options, but even after doing that the
'make' exited with an error 2.

I then tried installing, forcing the script to use the 11.04 settings
and it still exited with the same error 2.

As the HPLIP GUI is the only way to monitor ink levels it would be
really nice if this could be sorted before release.

When installing 11.10, it did recognise my printer and installed it, but
the scanner section of the printer and ink level monitoring do not work
with this basic install and the HPLIP GUI is needed for full
functionality.

Yes,

1. On the monochrome printers like yours, the "gdi" driver which is 
built into GhostScript works fine with simple documents: text, some 
graphics, ... On more complicated documents it can run into problems 
easily. SpliX prints all types of documents correctly and also supports 
more printer features.

2. There are also non-PostScript color printers from Samsung, they get 
support by free software for the first time with the SpliX driver.

Activating the CUPS snmp backend in Ubuntu Feisty

[Till Kamppeter]

Hi,

on the IRC I talked with pitti about activating the CUPS backends which
were de-activated by Debian by moving them into
/usr/lib/cups/backend-available. The three de-activated backends are
serial, scsi and snmp.

Most important is snmp, as it makes it much easier for unexperienced
users (our main audience) to set up network printers,

The CUPS backend snmp serves only for auto-detecting network-connected
printers in the local networks. It is called whenever CUPS is asked to
detect printers (via "lpinfo -v". entering the admin page or adding a
queue with the CUPS web interface, or adding a queue with most other
printer setup tools, like gnome-cups-manager, KDE Print Manager, or
printerdrake), It returns all detected network printers with there
correct URIs (using the ipp, lpd, or socket backends for printing). So
the user has only to click the auto-detection result and gets his
network printer running.

The detection is done by an SNMP broadcast asking for the printer MIB.
This is only answered by printers and so only printers and not other
SNMP-capable devices (like routers) get listed. This method is also very
fast. The result appears in 3 or 4 seconds, even in big networks. No
ping or portscan to unknown devices is performed and also no extra
daemon is started and no ports get opened. snmp runs only the mentioned
3 or 4 seconds and it runs as the cupsys user and not as root (no SUID).
So the impact to the system and the network is low. There are also no
broadcasts into the internet with the default configuration of the snmp
backend.

Issues which users have reported with problems of correctly detecting
printers of certain brands are fixed by Mike Sweet. So the backend is
currently in a very good shape.

It is also only needed for detecting printers, printing on the detected
printers is then done with the ipp, socket, or lpd backends, so the snmp
backend only gets invoked by printer admins to add a queue and never by
normal users. So security risks are very low and "printing just works"
experience is very high with it.

Pitti is, like me, in favour of activating it, but I also post here 
because in a certain form this is adding a feature after feature freeze.
So I want to know what is the general opinion about activating the CUPS 
snmp backend (and perhaps also the serial and scsi backends)?

For testing do

sudo ln /usr/lib/cups/backend-available/snmp /usr/lib/cups/backend/
sudo ln /usr/lib/cups/backend-available/serial /usr/lib/cups/backend/
sudo ln /usr/lib/cups/backend-available/scsi /usr/lib/cups/backend/

and then run the printer setup tools which are available on your 
machine. Set up the printers which are detected now and try to print on 
them via the new print queues.

For the implementation in Feisty the cupsys package only needs to create 
the above-mentioned links. No extra space on the CD is needed. Local 
admins can de-activate these backends again by removing the links, so no 
files need to be deleted or moved.

Re: Activating the CUPS snmp backend in Ubuntu Feisty

Do we use avahi for network printer discovery? How do I invoke a scan
for network printers via avahi? How is a GUI (GNOME/KDE) user supposed
to set up a network printer on a Ubuntu box?

As far as I know, the snmp backend of CUPS is the only tool to search
for network printers via SNMP.

Will Feisty+1 be the next LTS? If so, will the SNMP backend get
deactivated there again? Or why is Feisty better than Feisty+1 LTS when
activating the SNMP backend?

Call for testing: HPLIP 1.7.3

[Till Kamppeter]

Hi,

many of you probably have an HP printer and use it with HP's great free 
software driver suite HPLIP. Feisty has currently HPLIP 1.7.1 and this 
is probably what we get as final version as Feisty final will hit the 
mirrors in three weeks.

Unfortunately, HPLIP 1.7.1 has many bugs, see

https://launchpad.net/ubuntu/+source/hplip/+bugs

and the release notes of HPLIP 1.7.2 and 1.7.3:

http://hplip.sourceforge.net/release_notes.html

To get as many as possible of them fixed in Feisty, I have packaged 
HPLIP 1.7.3, but to get this into Feisty we need at least five positive 
testing reports (as we are already in Upstream Version Freeze). Please go to

https://launchpad.net/ubuntu/+source/hplip/+bug/98520

and do the steps in my "CALL FOR TESTING" (2nd and 3rd posting) and add 
your report, even if there are already more than five reports. The more 
the better.

I am very grateful for your reports.

Re: Introduction and Lexmark Printer Driver

[Till Kamppeter]

Also welcome to the list.

As I already told on the IRC I am manager of the OpenPrinting project 
and I also do printing stuff for Ubuntu.

Unfortunately, I have never done anything with the Lexmark Linux DDK, as 
I do not have a Lexmark inkjet nor did I have to package the DDK for a 
distro.

The reason why it is not in distros is that it contains closed-source 
parts. HPLIP made it into all the distros quickly because HP decided to 
release the whole thing as free software. So setting up HP printers 
usually just works under Linux.

I appreciate your work on getting actual drivers with the Lexmark Linux 
DDK. This will make many user's printers work. See all these posts of 
users crying for a driver on the Lexmark forum on OpenPrinting (you 
should post calls for testing there as soon as you have some code).

I will also look into whether your driver could be added to multiverse 
in Ubuntu (but this probably needs permission from someone from Lexmark).

Can you post a link to the current Lexmark Linux DDK site? Thanks.

CUPS 1.3.0-RC2 available for Ubuntu Gutsy now -- Please test!!

[Till Kamppeter]

Hi,

I have packaged CUPS 1.3.0-RC2, as we talked about on last week's 
developer meeting.

You can download the binary packages from

http://www.linux-foundation.org/~till/tmp/ubuntu/gutsy/cupsys13/binary/

and the source from

http://www.linux-foundation.org/~till/tmp/ubuntu/gutsy/cupsys13/

This is the new generation of CUPS, offering many new features (I hope I 
have activated all of them when compiling). See

http://www.cups.org/documentation.php/whatsnew.html

Please try it out. We need all your testing experience to be able to 
ship a Gutsy with a stable and not obsolete CUPS system.

NOTE: This CUPS runs as root, as pitti did not adapt his non-root 
patches to it. All other patches from Debian and Ubuntu are applied and 
so this CUPS should work as the original one from Ubuntu.

Re: CUPS 1.3.0-RC2 available for Ubuntu Gutsy now -- Please test!!

[Till Kamppeter]

The originally uploaded packages are broken. They have a bug which 
prevented CUPS from finding the PostScript PPDs, leading printer setup 
tools to assign generic PostScript PPDs or PCL PPDs to PostScript printers.

I have uploaded new packages with this problem fixed now. The files are 
at the same place and have the same names as the old ones. So everyone 
who has downloaded them already, please download and install them again.

I have also reported this problem upstream:

http://www.cups.org/str.php?L2464

Please install also hal-cups-utils and system-config-printer and test 
them with the new CUPS.

system-config-printer is Red Hat's printer setup tool and candidate for 
replacing gnome-cups-manager.

hal-cups-utils are scripts for HAL which set up print queues 
automatically when the printer is plugged (Plug'n'Print, 
https://blueprints.launchpad.net/ubuntu/+spec/automatic-printer-conf) 
and disable print queues of printers which are not connected or turned 
off. hal-cups-utils works currently only with USB printers.

Test system-config-printer by calling it from the command line and doing 
your printer administration with it (setting options, (un)sharing your 
printers, adding and cloning print queues).

Test hal-cups-utils by unplugging your USB printer and plugging it 
again. While it is unplugged, the queue is disabled and CUPS does not do 
unneeded retries of the jobs. As soon as you plug it it gets enabled 
again and all queued jobs get printed. To see automatic queue setup, 
remove the queues for your USB printer, unplug the printer and plug it 
again. After some seconds you have a new queue. In case of an HP 
printer, the queues are set up using HPLIP and if your HP MF device has 
a fax also a fax queue is created.

Re: Call for testing: new cupsys packages with AppArmor profile

[Till Kamppeter]

I have now merged these changes into my CUPS 1.3.0-RC2 packages. So you 
can test the AppArmored CUPS 1.3.0-RC2 now, too. Get the packages from

http://www.linux-foundation.org/~till/tmp/ubuntu/gutsy/cupsys13/

and the binary packages from

http://www.linux-foundation.org/~till/tmp/ubuntu/gutsy/cupsys13/binary/

Proceed with the testing like Martin Pitt already described. Especially 
report back the logs of AppArmor if you use the new authentication and 
networking features of CUPS 1.3.x.

Re: CUPS 1.3.0-RC2 available for Ubuntu Gutsy now -- Please test!!

[Till Kamppeter]

I have uploaded new packages again, but this time with -0ubuntu2 release 
number.

These add the new AppArmor support which Martin Pitt introduced as 
replacement for the now dropped non-root mode with the new 
cupsys-1.2.12-1ubuntu2. Please test these packages to see whether it 
also works well with the new authentication and network features of CUPS 
1.3.x.

See especially the output of

grep audit.*cupsd /var/log/kern.log

but also

/var/log/cups/error_log

The AppArmor profile is

/etc/apparmor.d/usr.sbin.cupsd

To make AppArmore enforcing it use

sudo aa-enforce cupsd

Please report your experience here.

Please keep hplip-gui also in main if the Kubuntu folks decide against

Re: Archive frozen for Gutsy release

[Till Kamppeter]

I have fixed the milestoned bugs

https://bugs.edge.launchpad.net/ubuntu/+source/system-config-printer/+bug/149529
https://bugs.edge.launchpad.net/ubuntu/+source/system-config-printer/+bug/149264

and packaged system-config-printer for them today, well before your 
freeze announcement, but unfortunately after my usual upload sponsors 
pitti and doko have left. Can you do the upload for me.

The package with debdiff is here

http://www.linux-foundation.org/~till/tmp/ubuntu/gutsy/system-config-printer/ 


The changes are very small and I have tested them and they really fix 
the two bugs.

The impact of the fix is rather high: Currently no Canon inkjet gets set 
up automatically even with Gutenprint supporting it and the job viewer's 
  menu entry goes into the KDE-only "System Tools" menu (so makes a menu 
for itself on non-KDE Ubuntu/Xubuntu/Edubuntu).

Here is the Debian ChangeLog:

-
system-config-printer (0.7.75+svn1653-0ubuntu2) gutsy; urgency=low

   * debian/patches/10_menu_entries.patch: Let menu entry for displaying
 queued jobs appear in the "Accessories" menu and not under "Systemn
 Tools". "Systemn Tools" is KDE-specific (LP: #149529).
   * debian/patches/20_match_more_printers.patch: Do best match by
 "most important word" case-insensitive. This matches especially
 the Canon printers correctly with the Gutenprint PPDs (LP: #149264).

Re: Need to update GhostScript package in the Ubuntu 7.10 (Gutsy) Repository

[Till Kamppeter]

Hi,

I have discussed this problem with the upstream developers of 
Ghostscript at Artifex and the problem is NOT fixed by the official 8.61 
release of Ghostscript. It appeared as fixed as the problem occurs only 
with Ghostscript built as dynamic library (the case for Gutsy) and not 
for a static build (the case for a standard "./configure; make; sudo 
make install" as users did with the official Ghostscript (which is not 
available as Gutsy package).

The Artifex developers are working on a solution and I hope that I can 
soon post it as a Stable Release Update for Gutsy.
