Please run the following command (it's all one line):

PYCUPS_DEBUG=1 python -c 'import cups; cups.Connection().printTestPage("Canon_i560_USB_1")'

What output do you get?

I'm having a similar problem and I feel like I'm getting so close. I just upgraded my Xubuntu distro from Dapper to Edgy last night with a surprisingly smooth transition despite what I saw in Bug #68027. One of the main reasons for doing so was due to the pain I had getting CUPS to work and reading that a print config was added. Still, I tried to print a test page from the utility and the bug report popped up. I didn't submit right away cause I wanted to look into it some more. Is it necessary to see this report? If so, is it stored anywhere? Sorry, still new to this and I couldn't find a Help/FAQ.

Anyhow, I tried the above Python one-liner and first got a segfault which created a new unrelated bug report. I just upgraded Python and got the following:

PYCUPS_DEBUG=1 python -c 'import cups; cups.Connection().printTestPage("HL1440")'
-> Connection_init()
<- Connection_init() = 0

I don't know what to make of this, but if it helps to know my system at all, I'm using a Toshiba Satellite 2805-S603 connected to a Brother HL-1440 by USB.

First of all, apport assigned this bug to the wrong package. The C code in the stack trace is from the Python bindings for CUPS, package python-cups. system-config-printer is pure python and therefore a platform-independent package, no C at all. pitti, can you look into this? I have moved the bug to python-cups now.

Second, I tried the Python one-liner, too, and it sends a job to my printer and gives no errors:

till@till-laptop:~/ubuntu/cupsys13$ PYCUPS_DEBUG=1 python -c 'import cups; cups.Connection().printTestPage("HP_LaserJet_3390")'
-> Connection_init()
httpConnectEncrypt(...)
<- Connection_init() = 0
httpClose()
till@till-laptop:~/ubuntu/cupsys13$

Perhaps this bug got already fixed in the upstream python-cups package.

Tim, have you an idea whether this got already fixed in upstream python-cups?

Merdyn, can you try again with Gutsy (if you do not want to install it, use a live CD)?

No idea. I was expecting the output from comment #6, with httpConnectEncrypt(...) -- I cannot account for that line not showing in the output in comment #5.

I have tried gutsy gibbon tribe 4 live session - and now my printer works just fine. It wasn't installed automagically - I had to use "Add printer". Printer was recognized as Canon i560, and after few clicks I could print a somewhat changed (from previous version of ubuntu) test page. I haven't tested printing photos and I don't know what all the advanced "settings" or "properties" (in printer properties) mean.
OK, my printer (Canon i560) seems to work properly with gutsy gibbon. Thanks for suggestion, Till.
PS. I haven't use linux for some time, and in the meantime changed motherboard and processor to AMD64 architecture.

Works in Gutsy
