I've noticed, that Canon Pixma ip4000 prints wrong colours and has other bugs, like horizontal white lines in bigger blue areas, also some yellow or red object are printed blurry in Feisty and Gutsy (gutenprint version 5.0.99 and 5.0.1), while Egdy version (5.0.0) works much better - I hasn't noticed any colour or other printing bugs).
I've compared gutenprint packages from Edgy, Feisty and Gutsy on Ubuntu 7.04 "Feisty" (backported gutenprint packages are at official Baltix GNU/Linux repository - http://ftp.akl.lt/baltix-linux/Baltix-Ubuntu-packages/feisty/gutenprint/ ) and I'm 99% sure, that Canon ip4000 Gutenprint drivers has big printing quality regressions in versions 5.0.99 and later (comparing to Gutenprint 5.0.0).
So, I'm 99% sure, that this bug is an upstream bug, maybe someone could report it in gutenprint sourceforge bug tracker and point upstream bug number here ?
