Till, After three days test running of printer including output of several dozens of pages, I confirmed that option "-o usb-unidir-default=true" just works for my printer, Canon Pixma MP600. In one case, I encountered printer just halt. In this case, I started printing with printer's power still off. And moreover, system went very unstable and I had to shut down the machine (and could not do safely). I convince that I can ignore this case and the option generally works. Thank you for your definite suggestions!
... One more excuse. Actually, I tried this option before, and it didn't work in that time ... cups and related packages were not updated. So, I had "double bugs" in that time and that's why this option didn't work. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/997040 Title: usb printer backend hangs when usblp kernel module is loaded To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cups/+bug/997040/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
