pycups
This page is about the Python bindings for the CUPS API, known as pycups. It was written for use with system-config-printer, but can be put to other uses as well.
I work on this module as part of my job at Red Hat.

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.
$ gpg –verify pycups-1.9.58.tar.bz2.asc

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:

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.
