Comment 76 for bug 997040

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.
