I've searched the forum for an answer to this specific question but haven't found one, but apologies if it has been addressed previously. I have a question about which driver setting (e.g., "Printer/Driver Matching," "ICM," "None," etc.) to select in the Canon printer driver inside Qimage Ultimate for cases where a custom media file for a third-party paper has already been created and uploaded to both the printer and the printer driver.

I'm using Qimage Ultimate (v2022.120) on Windows 10 to print on a Canon Pro-1000. I've used Canon's Media Configuration Tool to create a custom media file for the third-party paper I use the most (e.g., Canson Arches 88). I've also created a custom .ICC profile for that paper + printer combination using a spectrophotometer and profiling software (i.e., a Calibrite ColorChecker Studio and ccStudio software). Using the Media Configuration Tool, I've uploaded all the relevant adjustments/settings for the custom paper to the printer, itself, as well as to the Canon printer driver on the computer that I print from. In theory, the printer and printer driver should both now have all the information they need to produce color-correct prints when a user simply selects that custom paper in the driver (or directly on the printer, as the case may be).

However, when I open Qimage and select that custom paper from the media dropdown list, there's a popup in Qimage that seems to imply that the correct Canon driver setting to use is "ICM," which seems confusing to me. From my perspective, the custom media file that I've created should already provide all the information the printer needs to properly handle the paper and reproduce color-accurate prints, such that activating ICM would seem redundant or unnecessary.

Wouldn't "Printer/Driver Matching" be the more technically correct setting? My interpretation of that setting is that it basically means: "The printer will use the information contained in the custom media file to generate the print." Thanks in advance for the clarification.
