GIMP 2.6 Printing Problem with Ubuntu 8.10

Since my upgrade to Ubuntu 8.10 from 8.04 I am unable to print to my Canon PIXMA 145 printer. also when I print from Open Office Word processor only A4 and letter sizes print properly. When any Graphics or picture is included it prints very small also When I try to print a 4x6 picture in GIMP, I get a CUPS error message "pstocanonij write error, 32. Should I go back to Ubuntu 8.04 grrrr.
