AFAIK, if you're printing from LR, you can't use the Photoshop plug-in.
Right, the Photoshop Printing Plug-in only works for Photoshop.
So use ACPU and the 'standard' Canon print driver.
Can't do that. The printer driver is incompatible with ACPU. You can't select "No Color Management" under color mode when in ACPU. Canon makes use of 'special casing' and only allows "No Color Management" to show up in apps that are specifically named in a certain XML file that's installed with the driver.
Now, you might be thinking "That's the dumbest thing I've ever heard of" and you would be correct! But that's what they do and Doyle was brilliant in discovering this and he has given us an updated XML files with a bunch of additional apps named so that we can print with the No Color Management option. Everytime a new version of Lightroom or Photoshop comes out we have to update this darn XML file.
Anyway that's the deal. Out of the box, the printer driver isn't compatible with the ACPU so you can't print your targets through it unless you perform the aforementioned hack. Those that have Photoshop should simply install the wonderful Canon iPF PS Print Plug-in and print the target that way. That's THE longtime preferred way of printing targets on iPF pritners for many reasons. And yes, profiles can be used interchangeably between the driver, plug-in, PS, LR, Mac and PC etc.
