Comment 9 for bug 576058

I've updated to the proposed repo, but still can not print.

Then I tried to install Turboprint (trial version) ... amazing, the printer can print. But there is a strange thing, when I try to use the cups-gutenprint driver (probably able to print) still can not print, and when I try again using Turboprint driver, the printer can not print, and on the Turboprint status, show a message: printer not connected or switch-off and then the next message appears: usb_error: -1. To be able to print again, the printer must be turned off and then turned on again.

Indeed, with Turboprint can solve the problem, but I don't want to use it because I have to pay, better go back to Karmic Koala: p

Here I include cups error_log
