The printer supports automatic duplex printing, which means that the paper does not need to be rotated manually. The printer automatically rotates the paper to print on both sides.

The Brother HL-L2445DW printer does not come with toner included, so you will have to purchase it separately. Regarding compatibility with macOS 12.7.6 Monterey, I don't have specific information about this version of the operating system, but in general, Brother printers are compatible with macOS. I suggest you check the official Brother website to confirm compatibility.

No, this printer cannot scan. It is only a monochrome laser printer with printing functions, including automatic double-sided printing, but it does not have a scanning function.

I see no reason why it won't work with Chromebook... but it is only a printer, it is not a scanner. Non vedo alcun motivo per cui non funzionerà con Chromebook... ma è solo una stampante, non è uno scanner.
