[Bug 1032385] Re: USB timeouts with Canon iP4300

2013-12-28 Thread Simon Clift
I can confirm the bug and the fix with a different model of printer:
   * Canon iP4500
   * TurboPrint 2.30-1
   * KUbuntu 13.10, Kernel 3.11.0-14-generic #21-Ubuntu x86_64

Before fixing the uni-directional access flag I would be able to print a
single job after rebooting or power cycling the printer.  After the
single job I would get a message "Printer status failed - no access" in
the TurboPrint Monitor application.  With the cups LogLevel=debug I was
unable to spot anything particularly wrong.  At LogLevel=info I was not
seeing any useful messages.

Applying the fix (Comment #10 above) I am able to print multiple jobs
(several test pages) with no trouble.

Thanks for the fix. If you have time for answering (I am curious):

1. Why has this become a problem in Ubuntu 12.04 since it worked before?

2. Even though I fix it myself due to time constraints: Would there be
any advantage in making bi-directional communication working? E.g.
support for ink level control or color print head calibration?

3. What scope does your fix apply? Also vanilla cups (which is also e.g.
used on MacOS) or specifically on Ubuntu-specific features?

Thanks again for the quick solution!

Thank you very much.

So everyone suffering this bug has the Canon Pixma iP4300, so I will add
a quirk rule to the USB CUPS backend to do only uni-directional
communication with this printer.

Everyone, to worjk arounbd this problem please run the following command
in a terminal window:

lpadmin -p  -o usb-unidir-default=true

2012-08-09 Thread tigerente
Thanks. First of all, the "blacklist usblp" only seemed to have an
effect on some type of printings. Photos with high quality settings
still failed when printing over network to my ubuntu print server (32bit
by the way). Data size problem?

Anyhow, I removed the blacklist usblp (even manually loaded it then
successfully) and until now the usb-unidir-default=true seemed to do the
trick (have not tried no-reattach-default=true since it was suggested as
a backup workaround).

I will post my new findings here again if things do not work and would
volunteer for testing ppa updates that do not require the unidir-
setting.

2012-08-09 Thread Till Kamppeter
Can you all remove the blacklisting of usblp and then try to force uni-
directional access to your printer via

lpadmin -p  -o usb-unidir-default=true

Does printing now work correctly? If not, remove this option via

lpadmin -p  -R usb-unidir-default

and try blocking the re-attaching of the kernel module after printing
via

lpadmin -p  -o usb-no-reattach-default=true

Try also with both options.

Turn off and turn on your printer before each test.

Affects me as well, same errors as described above, also after doing a
dist-upgrade today.

The update seemed to have a newer cups-version in the main feed than in
Till's ppa.

Adding "blacklist usblp" in /etc/modprobe.d/blacklist.conf solves it (as
a workaround, inspired by 997040).

- plugging USB cable into a different USB port did not help
- CUPS status on http://http://localhost:631/: "Rendering completed"
- even if the print job is completed successfully, some lines on the page are 
missing (between 4 and 10 lines on an A4 page).
