When you say they "don't work" do you mean that you are getting poor print quality? I have an iMac and the R1800 and it works OK, but then again, maybe my standards aren't as high as yours.........I have to mess around with the setup and I get better results by changing the settings to use the printer to manage the printing process rather than Photoshop.
All said, the new Leopard Intel print driver isn't as good as the previous version for the Tiger operating system.
Should have remembered your problem todd
has you hair grown back??
The mac sends the message to the printer but the quality is a horror .I have looked at many mac forums and it is big well known problem It can only be solved by selling the printer so it up for sale .
PS::hooked up a friends Canon 9500 and worked 95% 0n the first print then added paper profile and pix are 100%
