Who is correct? Grok Ai vs Martin Evening's LR 5 book re: LR compensates the shadow point for print

#2 "Managed by Printer" -- a) it doesnt mention anything about black point compensation, but I assume it is still doing it?

By @Hmmokthen

Printer drivers tend to be a “black box” where advanced features such as black point compensation might be done automatically but not controllable and without options exposed to the user.

For desktop inkjet printers, I believe black point compensation is based on information stored in the media type or profile. For example, I use Epson photo inkjet printers, so if I have the printer manage the color, I think black point compensation will depend on whether I selected a media type of Plain Paper, Epson Enhanced Matte Paper, Epson Premium Luster Photo Paper, etc. in the Epson-specific printing options. The printer driver includes density and white point info for each of those papers, so it can adjust black point compensation for each of them, as long as I chose a media type that matches the paper I put in the printer.

b) "remember to enable color management in the printer driver dialog box" --where is this, cant find it anywhere?

By @Hmmokthen

The example below is for Epson printers, where you choose the color management system in the Color Mode menu. On a Mac, that’s in the Print dialog box, Printer Options category, Printer Settings dialog box.

I don’t know how the options are arranged by Canon in their inkjet printer driver software, but hopefully this will point you in the right direction.

On macOS, Lightroom Classic and the Epson printer driver are properly coordinated so that if you choose a profile in the Lightroom Classic Print module, causing Lightroom Classic to manage the color conversion, when you go into the Color Mode menu, Off (No Color Management) is already set and can’t be enabled, as on the left in the picture below. On your Canon, you might have to manually disable color management, but again I’m sorry that I don’t know where that is or how it works in the Canon printer driver.

If you choose Managed by Printer in the Lightroom Classic print module, color handling is handed to the printer driver. On an Epson, as shown on the right in the picture below, this defaults to setting the Color Mode menu to Epson Standard (sRGB), which is often appropriate.
