I just started using iPhoto to print pictures a few days ago. I am running version 6.0.6 of the application in Mac OS 10.4.9.
Some pictures print just fine from iPhoto with my Canon iP 4000 (latest driver installed).
Other pictures do not print. The printer just feeds the paper through without printing anything.
The photos that do not print also do not export to Preview from the print pane in iPhoto.
Any ideas? Thanks.
