I saw a presentation by a Canon rep at Calumet's open house today. There was not a lot new, but she did project the driver dialogue on a Mac onto a screen & showed a number of 16-bit profiles that she said are coming out "later." I mentioned the poor documentation (praised the print quality) & asked about more info on media settings. I did not fully catch & understand her answer. I think she said that the paper names are being translated (into Japanese?) at the printer & they are adding more translations. She recommended using Special 1 through 5 for non-Canon papers, 5 providing more ink. (Her profiles were like "S5" for (Special 5), 16 pass, highest. I asked about using the closest Canon paper to the type we are trying to use. She did not appear to encourage that. She said she would email me something next week that might help. If it's different than what is available on the wiki, I'll let John know.
I met a very nice guy there, whose name I now can't recall, who uses a Mac G5, I think. He said he had tried to use the iPF5000 with a USB hub, but it worked intermittently, so he was going to getting a longer USB cord & direct connect. When I mentioned I could not make the ethernet work, he said to try a "crossover" cable. I had not been aware of that requirement, if it works, or seeing it in the Canon documentation.
