Welcome to HP Support Forums. 🙂 

I came across your post and would like to help. 

I understand that you have an HP Color LaserJet Pro MFP M277dw and are unable to change the settings to print in black only from your Mac computer. 

I recommend you to perform the following steps to isolate the issue and arrive at a fix: 

1. Click the Apple menu, then click System Preferences.

2. Depending on your operating system version, click Print & Fax, Print & Scan, or Printers & Scanners.

3. Check if the name of your printer displays in the Printers list. Do one of the following steps, depending on if the printer is listed or not.

   • If your printer is listed, remove and re-add the printer to confirm communication and to make sure the correct driver is used. Click the name of your printer, then click the minus sign  to delete the printer. Once the printer is removed, click the plus sign , click Add Printer or Scanner, click the name of your printer, then continue to the next step.

   • If your printer is not listed, click the plus sign, click Add Printer or Scanner, click the name of your printer, then continue to the next step.

   • If your printer is not listed in the Add Printer or Scanner window, make sure the printer is connected to the Mac with a USB cable, or that it is on the same wired or wireless network as your Mac. See the Frequently asked questions to resolve connection issues, try to add the printer again, then continue to the next step.

4. Click “Print Using...” or “Use”, and then select Secure AirPrint or AirPrint. Alternatively, you may select the name of your printer if available in that list.

Please refer to the information mentioned in "Color and black & white settings" from this HP document: http://hp.care/2FRVcX3

In case the issue persists then let us reset the printing system i the Mac OS. By doing this it will remove drivers for all the printer drivers that were installed in your Mac computer

• Click the Apple menu, and then click System Preferences.
   

  

• Click Printers & Scanners, Print & Scan, or Print & Fax.

• Right-click (or Control + click) anywhere inside the Printers window, and then click Reset printing system.

• Click Reset or OK.

• If prompted, type your username and password, and then click OK.

  The printing system resets.

• Turn off the printer, wait 5 seconds, and then turn on the printer.

• Wait until the printer is idle and silent.

• In the Printers window on the Mac, click the Add button .

• Confirm AirPrint or Secure AirPrint displays in the Use or Print Using menu, and then click Add.

I genuinely hope the issue gets resolved without hassles and the unit works great.

Let me know what happens. I'm always here to assist you.

Cheers! 🙂
