Converting a color PDF to B&W on your Mac. The Preview app comes installed on every Mac. 1) Open a PDF file in Preview on your Mac. TIP: Use the Print dialog box in any app and then click the PDF popup menu at the bottom of the window to access the option to open the current document as a PDF file in the Preview app. MacOS Feature Availability. Some macOS features are not currently available in every region or language. Choose a feature below to see if it’s supported in your region and language. If your Mac is using an earlier version of any Mac operating system, you should install the latest Apple software updates, which can include important security updates and updates for the apps that are installed by macOS, such as Safari, Books, Messages, Mail, Music, Calendar, and Photos.

One can manually configure Mac OS X Lion and Mountain Lion to default to Black and White printing, and have it return automatically to the Default Settings after printing with another preset.

Changing the Default Settings values is the challenge. Lion and Mountain Lion can be easily changed to automatically return to the Default Settings every time after printing.

Note: This How-to requires an Administrator login to complete at Step 10

22 Steps total

Step 1: Open Safari and enter http://127.0.0.1:631

The address 127.0.0.1:631 is where CUPS is located. If this is the first time accessing CUPS (the Common Unix Printing System) a warning dialog will be displayed.

Step 2: Open Terminal and enter the command in quotes above.

Terminal is located in the Utilities Folder which is found in the Applications folder. Enter the command inside the quotes on the web page and hit 'return'. If it is typed correctly the the Path $: should be repeated.

Close Terminal. Terminal in Mac OS is similar to the Command line in Windows and should not be left open.

Step 3: Refresh the Safari window to see CUPS

Command R or select Reload/Reload Page in the View menu. The CUPS menu should display.

Step 4: Select the Printers Tab

A list of all of the printers that have ever been set up on the computer should be here.

Step 5: Select a printer.

For me this works for Color laser printers and Copiers. My HP inkjet print drivers do no allow a Black only selection.

Step 6: In the Administration button choose 'Select Default options'.

The Administration button is located beneath the printer name. Click on it and select the 'Select Default options' option.

Step 7: Select the General Tab

This display is where the Color / Black & White option is found.

Step 8: Set 'Color mode:' to 'Black & White'

Color is not the only setting that can be changed. My standard configuration is:
Duplex: 'Long Edge'
Color Mode: 'Black & White'
Staple: 'Top left'

If the printer can not Duplex or Staple the commands will normally be ignored.

Step 9: Click on the 'Set Default Options' button.

Step 10: In the dialog box enter an Administrator's name and password

Finish by clicking on the highlighted 'Login User' button.

This dialog box may not display if an Administrator has already be in CUPS.

This can be the user's login if the user is an Administrator. It is becoming common for the user of a computer to be at a Standard level user. In this case it will be necessary to have an Administrator complete this dialog box.

Step 11: Defaults are changed

Step 12: Making the computer always return to the Default setting is easier

Step 13: Start a Print job.

Using the open Safari window (or almost any printable window) select 'Print...' from the Edit menu or 'Command P'. In the bottom left of the Print Dialog box click on the 'Show Details' button if necessary (if the button is already 'Hide Details' then it is not necessary).

Step 14: With the Print menu in Show Details mode click on the 'Presets:' button.

Step 15: And select 'Show Presets...' from the menu.

Step 16: At the bottom of the dialog box select the check box for resetting to defaults

Select the check box for 'Reset Presets menu to 'Default Settings' After Printing. And click on the 'OK' button.

Step 17: Done.

The default printing session is now Black & White.

Step 18: Adding a Color Preset.

Now that the Default setting is B&W it it now necessary to create a preset for Color. This also can be done from the Print dialog box while the Details are showing.

Step 19: Make your changes to 'Printer Features'.

Step 20: Going back to 'Presets:' Save and name the new preset.

Choose 'Save Current Settings as a Preset...'. Name and Save

Step 21: Name it and click on the 'OK' button

Step 22: Cancel or Print and the setup is done.

Apple has not made this easy yet. The CUPS user interface has been improving with each update of OS X. Hopefully it will soon be as easy to make a change like this in OS X as it is in Windows.

  Super directions!:->...We were stuck on getting the CUPS web page up ...I just wish there was a way to deploy certain printer settings to like 300 MacBook Air units all at the same time...Looks like it is going to be one-on-one basis..:-<

  Thanks for this interesting info. Any idea why some options are listed twice in the printer properties? For example, for my Canon Pro9000 II, 'Grayscale printing' appears twice, and there's 'print quality' and 'quality' (both of which contain the same options).

  A solution could be modifying the .ppd file into /etc/cups/ppd with a sed command. This is an example for a BizHub C654e :

  sed -i bak -e 's/DefaultKMDuplex: Single/DefaultKMDuplex: Double/' /private/etc/cups/ppd/.ppd

  The -i creates a copy of the original file, useful if it doesn't work.

  Terrific! Thank you for putting in this time. Helped me out.

Apple Mac OS 8 was another major overhaul of the OS from the earlier Mac OS 7. It added a new Platinum visual theme, a multi threaded Finder, better virtual memory, and many customization options. 8.5 and later require a PPC CPU. It was followed up by Mac OS 9.

Running MacOS 8 requires a supported Motorola 68K or Power PC based Macintosh (see the compatibility matrix), or one of the following emulators:

Basilisk II - Runs MacOS 7.x-8.1, emulates later color Motorola 68k based Macs.

SheepShaver - Runs MacOS 7.5.2-9.0.4, emulates a Power PC based Macintosh.

Installation instructions

Mac OS 8.5 and later require a PowerPC based Macintosh. This version drops support for all m68k CPU based Macintosh computers.

Emulation notes: To run MacOS 8.5 on newer hardware, we recommend the SheepShaver emulator, which emulates a PowerPC Macintosh.
