Canon provides a PS-plugin named "Easy-PhotoPrint Pro v. 2.7.2" and recommends to print utilizing this plugin (file -> automize -> easy photoprint pro) instead of the normal print dialogue. The results are good, however I cannot choose my paper/printer specific icc profiles which is provided by Hahnemühle specific for this printer.
The results from PS´s regular print dialogue using the specific icc profile are disappointing: contrast is not only very poor but looks very different from my (calibrated!) display.
