@Samuel Santos,Thanks for posting in Q&A.
From your description, I know you want to configure printer to print only in black and white via Intune.
Based on my research, there is no direct feature in Intune, however, we can create a PowerShell script to set printer to print only in black and white.
Here are some steps you can refer.
1.Create a .ps1 file with the content below and manually test it on one device.
#Get the name of the printer
$printerName = "Your Printer Name"
#Set the printer to print in black and white
Set-PrintConfiguration -PrinterName $printerName -Color $False
2.If the script work properly, then upload it into Intune and configure as below.
3.Deploy it via Intune, then it will work.
Hope it will help.
