[Desktop-packages] [Bug 1062617] Re: No network scanner autodetection by backend kodakaio
I did a trial with a live DVD. Ubuntu 16.04 A network connected kodakaio printer can be auto detected. (I think that's with avahi) scanimage -L lists the printer.

What I meant was that it was not worth working on autodetection using cups, when the method had changed to avahi. I do not know if the avahi autodetection works for everyone, though I have not seen many complaints about that. But I guess I should be able to test it by seeing if the live DVD can autodetect a kodakaio printer. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to sane-backends in Ubuntu. https://bugs.launchpad.net/bugs/1062617 Title: No network scanner autodetection by backend kodakaio Status in sane-backends package in Ubuntu: Triaged Bug description: sane-backends 1.0,.23 in ubuntu 12.10 has a new backend kodakaio for kodak aio printers The backend can autodetect network connected scanners using functions in cups.

Re: [Desktop-packages] [Bug 1500636] Re: commands passed to cups fail. File missing
Till,
system-config-printer version 1.3.8 works
version 1.5.6 does not work.
My impression is that the command file generated in printerproperties.py
using
with tempfile.NamedTemporaryFile(mode='wt') as tmpfile:
tmpfile.write ("#CUPS-COMMAND\n%s\n" % command)
has a size of zero bytes when the job is submitted to cups
maybe due to buffering?
in the older working version 1.3.8 the command file is generated using
(tmpfd, tmpfname) = tempfile.mkstemp ()
os.write (tmpfd, "#CUPS-COMMAND\n%s\n" % command)
os.close (tmpfd)

More investigation: Using ubuntu live DVDs : commands in system-config-printer of ubuntu 13.10 work OK. In ubuntu 14.10 they do not work. I uninstalled system-config-printer 1.5.6 from my xubuntu 15.04, then installed version 1.3.8 The commands work OK.

[Desktop-packages] [Bug 1500636] Re: commands passed to cups fail. File missing
Till, The printer is a kodak aio hero 9.1 and the driver is my c2espC driver, with command filter command2esp. This all used to work, for both print self test and clean heads. But recently I noticed that it no longer worked. However, if I make a text command file called "selftest" containing #CUPS-COMMAND PrintSelfTestPage and then send that page to the printer via cups using lpr selftest The printer does generate its selftest page. So it seems like cups and my command filter still work. That makes me think this could be a problem with system-config-printer. Do these command buttons in system-config-printer currently work for other printers that have command filters? -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to system-config-printer in Ubuntu. https://bugs.launchpad.net/bugs/1500636 Title: commands passed to cups fail.

Just for information. Later versions of sane-backends will auto detect the kodak AiOs using avahi instead of cups.
