I have a Canon i560 installed on an ubuntu 12.04. When I print the print test page, the "ubuntu" brand name which is black and the black circles don't appear. But the black text in the lower part and the black frame does appear. I can supply a scanned image of the printed sheet if needed (I cannot upload it because I'm a new user...)
When I print from acrobat reader or from google chrome, the resulting page miss black text (some text appear, other won't). Printing from LibreOffice or Firefox work well. The configuration of the printer should be ok since I'm able to print correctly from LibreOffice and firefox. I configured the printer in CMYK mode.
Is it a bug related to ubuntu 12.04 (I never had any problem with previous version but I'm not sure the problem appeared with the upgrade to 12.04) or did I miss something ? If it's a bug, in which package do I have to report it ?
Thank you.
