Hey Tim,
trying to use pycups on RHEL5 but can’t even get it to build. I get the following;

Any hints?
Also, in the setup the package is referred to as “cups” rather than “pycups” which will result in an RPM being produced called cups-1.0 which isn’t what you want (I assume).
TIA
Cheers
Dan
Dan: run ‘make’ to build pycups — the VERSION macro comes from the environment set up by the Makefile.
For packaging, I use ‘cups’ for the name because I want to import the extension with ‘import cups’.

Yes, it is used extensively by system-config-printer, in particular the cupshelpers.py file.
There is also documentation for it included in the pycups source tarball: try ‘make doc’.

Hi,
After making the application if I run the example I get: undefined symbol: libiconv. I have libiconv 2.4.0 installed
Any idea?
pycups doesn’t use the symbol ‘libiconv’ directly, however it does use ‘iconv’, ‘iconv_open’, and ‘iconv_close’. These are POSIX.1-2001 functions, so should be provided by your C library (for instance, GNU glibc provides them).
Your source does not build on Mac OS X. Here is a patch.
Btw, there are C libraries other than glibc…

I think your patch has been broken during transit. Please submit patches in unified diff format (i.e. diff -u), preferably from ‘git format-patch’, using the trac interface or normal email.
However, for this particular case it looks like it needs an autoconf check, which means that it needs to start using autoconf.
I would prefer to email the patch but I can’t seem to find your email.
However, the modifications I made to the Makefile regarding libiconv seem to have been futile. Python throws the following error when I try cupstree.py
(right after running make install):
Traceback (most recent call last):
File “pycups-1.9.30/cupstree.py”, line 2, in
import cups
ImportError: dlopen(/usr/local/lib/python2.6/site-packages/cups.so, 2): Symbol not found: _libiconv
Referenced from: /usr/local/lib/python2.6/site-packages/cups.so
Expected in: dynamic lookup
I noticed that I was able to import cups if I launched python while standing in the source directory where the freshly build cups.so can be found. So I manually copied cups.so to /usr/local/lib/python2.6/site-packages and now I am able to import cups regardless of where it’s started from. Indeed, running cmp on the cups.so that is created by make install and the cups.so that is created by make shows the files are not identical:
> cmp /usr/local/lib/python2.6/site-packages/cups.so /Users/kajic/stuff/kek/pycups-1.9.30/cups.so
/usr/local/lib/python2.6/site-packages/cups.so /Users/kajic/stuff/kek/pycups-1.9.30/cups.so differ: char 17, line 1
How can this be?
I realize I am probably missing out on something but why isn’t it possible to add jobs using pycups? I would very much like to be able to do this and I’ve looked through the pycups documentation but I can’t find an addJob or equivalent method. Right now I am using os.execv and “lp” to add jobs but I would very much like to avoid that. Perhaps there is some other library I could use to add jobs?
Robert: use cups.Connection.printFile()/printFiles() to do that.
cups.require(“1.9.39”)
Thanks again! I was using 1.9.30 🙂
Here are some notes on what I had to do to sucessfully install 1.9.45 (Max OS X 10.5.6):
In cupsppd.c I had to remove the #ifdef __SVR4 on line 510 (and 528) because otherwise gcc gave the following warning:
cupsppd.c:557: warning: implicit declaration of function ‘getline’
and when importing cups in python I got the following error:
>>> import cups
Traceback (most recent call last):
File “”, line 1, in
ImportError: dlopen(/usr/local/lib/python2.6/site-packages/cups.so, 2): Symbol not found: _getline
Referenced from: /usr/local/lib/python2.6/site-packages/cups.so
Expected in: dynamic lookup
Furthermore I had to add LDFLAGS=-liconv to line 12 in the Makefile. Then after a make and make install I had to manually copy cups.so from the source directory to its install location:
sudo cp pycups-1.9.45/cups.so /usr/local/lib/python2.6/site-packages/cups.so
Indeed, as I said in a previous post, pycups-1.9.45/cups.so and pycups-1.9.45/build/lib.macosx-10.3-i386-2.6/cups.so seem to differ:
> cmp pycups-1.9.45/cups.so pycups-1.9.45/build/lib.macosx-10.3-i386-2.6/cups.so
pycups-1.9.45/cups.so pycups-1.9.45/build/lib.macosx-10.3-i386-2.6/cups.so differ: char 17, line 1
I hope this can be of some help to others.
I would very much like to avoid that. Perhaps there is some other library I could use to add jobs?
JohnT: are you talking about on Mac OS X? You can use libcups directly, of course.
The package doesn’t build properly on fc10

Fixed upstream (add “tls->” just before “cups_password_callback” at cupsmodule.c:155).
However, be aware that Fedora 10 is no longer receiving security updates — you should upgrade to a newer version of Fedora.
Hm, it fixed the first error.
The others are still there :
namely the whole
cupsmodule.c:342: error: ‘struct TLS’ has no member named ‘cups_password_callback_context’
cupsmodule.c:342: error: ‘struct TLS’ has no member named ‘cups_password_callback_context’
cupsmodule.c:342: error: ‘struct TLS’ has no member named ‘cups_password_callback_context’
cupsmodule.c:342: error: ‘struct TLS’ has no member named ‘cups_password_callback_context’
cupsmodule.c:343: error: ‘struct TLS’ has no member named ‘cups_password_callback_context’
Could it be due to the fact that I have cups 1.31 and not 1.4 ?
Ok I removed the 2 lines referring to the cups_password_callback_context and was able to compile.
Now there is another problem when trying to run some package using pycups (namely cloudprint).
ImportError: /usr/local/lib/python2.6/site-packages/cups.so: undefined symbol: cupsGetPPD3
It is most likely due to the fact that I have cups 1.31 .
Any way to force the build so it uses 1.31 ?
Both problems also fixed in the git repository now.
Thanks,
Actually I fixed them myself in the code and recompiled 🙂
I also had a problem with getPPD3 and have to comment out the appropriate functions as well.
Anyway it works fine now with the cloudprint.
I am also getting this ImportError when starting the python cloudprint script:
ImportError: /usr/local/lib/python2.6/site-packages/cups.so: undefined symbol: cupsGetPPD3
Can you point me in the direction where to comment out the appropriate functions so this error will not occur?
My OS is Ubuntu 8.04 server with python 2.6 and pycups-1.9.55 installed.
Thanks
Rogier: you need a newer version of cups or else wait for pycups-1.9.56 which will work around compiling against older versions.
very good work, it could be very helpfull to have an intro / tutorial whit the basic
something very easy just to start using the module
#Connect to CUPS whit the default user
printer = cups.Connection()
#Define the default printer name
default_printer = printer.getDefault()
#Print a Test Page in the default printer
printer.printTestPage(default_printer)
#Print a file whit the default options
printer.printFile(default_printer,”PATH/FILE”,”Title”,{})
perhaps some example adding a printer, etc…
i know it s very noob but it can save some time to a lot of people, i dind’t find any tutorial on the web and didn t know if this module could do the stuff i need until i build it and ask help(cups)…
Yes, good idea. Or maybe I should make it a bit more like pysmbc and have the full documentation online.
Great lib! After some problems everything works like a charm 🙂
Hi Tim,
Thanks for releasing this py binding library. Made my development time much shorter and I didn’t have to put in a lot of effort to write using C library.
I could accomplish most of my tasks using pycups library. However, there is one API component which is available in C library but not exposed through pycups library, i.e cupsAdminExportSamba.
I managed to write the PyObject method to extend pycups library for this API call. But, the major constraint is that this call relies on cups-windows drivers to be available on the local machine alongside with libcups. Now, I am not sure how this fits into the pycups library when there is an additional dependency. Perhaps, you have better idea.
It just needs to behave the same as the libcups function would.
One (rather ignorant) question, How do I send you a pull request(like github) for you to check the changes I have made?
Just let me know the URL to your git repository and I can take a look.
Here the commit to my git repository.
https://github.com/narisipalli/pycups/commit/068357df8a6868ad679ed4941282d64f5d2713d0
Thanks. One comment:
+ char str[80];
[...]
fgets (str, 79, tf);
That would be better as:
fgets (str, sizeof (str), tf);
and perhaps a comment explaining what that file is expected to look like and why the last line is relevant in this situation.
(Note that fgets already leaves space for, and stores, a terminating nul character.)
Thanks for looking into it. Took some time to come back to this, blame on holiday time.
Heres my commit with changes as per your suggestions-
https://github.com/narisipalli/pycups/commit/38911235208055324299a4df6699672528ffccc6
Thanks. Some warnings when building though:
upsconnection.c: In function ‘Connection_adminExportSamba’: cupsconnection.c:3808:13: warning: ignoring return value of ‘fgets’, declared with attribute warn_unused_result [-Wunused-result]
Should really check this.
cupsconnection.c:3817:8: warning: attempt to free a non-heap object ‘str’ [enabled by default]
I didn’t spot this when looking through first of all, but str is declared on the stack so we don’t need to free it.
When I import your git repository it has a separate history of its own instead of branching from mine… isn’t it meant to share a common ancestor?
Thanks for pointing out these issues.
Modified the fgets code to avoid compiler warnings and also removes the new line character that comes along with fgets.
I cleanup with the commit history to push to github earlier. I shouldn’t have done that. I overwrote my previous commits to keep the index intact. I lost some of the interim commits(No big deal!)

Thanks, merged.
Thanks. When are you planning to push the tar of the new version 1.9.58?
I’ll probably get to it this week.
macaronij: the new 1.9.58 release is now registered at PyPI and the documentation is there as well. See links in the main page, above.

I had to update Makefile for Source Mage GNU/Linux. You changed in this version ln -sf to mv for cups.so, I had to change it back.
sed -i ‘s:mv build/lib:ln -sf build/lib:’ Makefile
Source Mage commit:
http://scmweb.sourcemage.org/gitweb.cgi?p=smgl/grimoire.git;a=commitdiff;h=d831437ebbebfa020aa4176058f8c565e1a41908;hp=f31d661af73c9265c983523514dc615d60eb0e16
GPG signature fixed: the signature I still had here on disk was the same, most likely a memory issue that was fixed in the last few weeks.
I’ve applied your other change.
I tried posting a ticket on trac but there’s no registration page ?
Anyway, requested_attributes doesn’t seem to work in Connection.getJobs(). It will always return an empty dict. It works with getJobAttributes though. Let me know if you need more details.
While I’m at it: your software is awesome 🙂 I added print support with full option handling to my django web app in a day of coding. Thanks a bunch!
The registration is the Fedora Project registration.
What version of CUPS are you running? That might very well make the difference…
Sorry I forgot to mention: 1.9.51-0ubuntu2
If that’s fixed in a newer version sorry for bothering, otherwise I’ll open a ticket when I get back at the office on monday.
That’s a pycups version number; what about CUPS? pycups just returns whatever CUPS tells it to.
cups is 1.4.4-6ubuntu2.3
I’m using ubuntu 10.04.3 LTS.

I seem to be missing some bits. This is on a FreeBSD 8.2 system with cups 1.5.2 installed. I’ll reinstall it in a minute and see if that clears it up. Not sure about the python bindings for avahi which I guess I also need…

I left a comment about building this on FreeBSD: turns out its in the ports collection there.
Thank you for writing this wonderful module. It defiantly will make my time working with printer abstractions in UNIX much easier for my program.
Question though: is there any attribute or method to find what is marked as the default printer with? All I could find in the documentation about it is CUPS_PRINTER_DEFAULT, but I’m not sure where this is exposed in the actual printer attribute list.
cups.Connection.getDests() returns a dict whose values each have an is_default attribute. That will reflect the user’s personal default setting.
To find out which is the default printer for a given server, examine the ‘printer-type’ attribute in the return value of cups.Connection.getPrinterAttributes(): it is a bitmap, and CUPS_PRINTER_DEFAULT is one of those bits.
can someone help me out?

net-print/cups-1.6.0 USE=”X acl dbus filters pam python ssl threads usb -avahi -debug -gnutls -java -kerberos (-selinux) -static-libs -systemd -xinetd -zeroconf”
There are some fixes since 1.9.61 for CUPS 1.6. I’ll make a new release soon.

I just updated CUPS from SVN and it did not help any.

Hi, I’ve been installing cups with pycups without an issue for a couple months, but since early December, we’ve been running into this issue when we perform the command: sudo pip install pycups.
A lot of errors appear similar to this:
cupsmodule.c:1282:3: error: ‘IPP_OP_PRINT_URI’ undeclared
cupsmodule.c:1284:3: error: ‘IPP_OP_CREATE_JOB’ undeclared
etc. etc. The errors seem to all have to do with IPP_OP_something something.
Any assistance would be greatly appreciated.
These ‘IPP_* undeclared’ errors are fixed in pycups-1.9.71.
Hi Tim,
Thanks for that – any ideas when we will see a 1.9.71 release on pypi?
Cheers,
Gav
Thanks for reminding me. I’ve released 1.9.71 today.
Thanks Tim! I’ll update when I get back to work on Monday!

Oops, sorry. I released 1.9.72 yesterday to fix this.
Seeing a massive number of the “undeclared (first use in this function)” errors when building on:

Should be fixed now in master.
Thank you, built fine. Very much appreciate your time to fix.
Thank you for pycups. I’ve had a good time with it for the past few days. I am working on a small project that archives local print jobs for retrieval and analysis. To this end, I found a Redhat email post by you on “CUPS Configuration: Get-Notifications”.
Could you please take some time to elaborate on `Connection.createSubscription()` method?
Specifically, what do the parameters `uri`, `recipient_uri`, and `events` mean?
Hi,
As pycups is simply a wrapper around libcups, the best thing to look for is the CUPS documentation.
If you can’t find what you need there, as CUPS is an implementation of IPP the next step is the IPP specification.
Here’s a start for CUPS:

Hi Tim,
Thank you for pycups. I use it in several software and it’s work perfectly.
I have a question. Is there a way to print several file if I want to specify different option (to change paper bac for example) for each file ?
Perhaps cups.Connection.printFiles function reply to my question but how to specify options for 1rst document, options for second document, …
Thank’s by advance for your answer.
Have a good day.
Gael
No, I think you’d have to issue separate requests for that.
Hi Tim,
thank you for pycups. i want to know how to use pycups,but i can’t open the website of the document?can you help me ?
Unfortunately pythonhosted.org documentation can no longer be uploaded so I’ve removed it.
To see the documentation, run ‘make doc’ once you have unpacked the tar file.
