I've installedand configured my printer many times with this guide: https://help.ubuntu.com/community/CanonCaptDrv190
I've tried 2.4 and 2.3 drivers but noticed no difference. At first installed by using guide to 12.04 as I have that version on ubuntu. Then tried the longer version. And mixed them up and googled a lot.
Now I'm in situation that captstatusui doesn't show anything at all. Gui launches but all fields are empty. When I try to print a test page it tries to process a while and gives me this error message: ccp send_data error, exit
