How to Print a PDF in Grayscale Using Adobe PDF Printer
Question details
The user needs to print a document to PDF in grayscale using the Adobe PDF virtual printer.

- Product
- Adobe PDF Printer
- Device & OS
- not provided
- Scenario
- Attempting to create a pure black and white PDF file via the virtual print dialog.
- Observed behavior
- The standard 'Print in Grayscale' option is greyed out, and selecting 'Black & White' in the printer properties still produces a color document output.
Verify that your source application (such as Microsoft Word or your web browser) does not have hardcoded color management settings overriding your virtual printer preferences.
Use an Advanced Grayscale Color Profile
Force the Adobe PDF printer to convert colors to black and white by assigning a commercial grayscale color profile like Dot Gain.
When standard grayscale settings fail or are disabled, the virtual printer might still be relying on an RGB or CMYK color profile. Manually selecting a single-channel 'Dot Gain' profile guarantees that the output will be restricted to shades of black.
Open your document and navigate to File > Print.
Choose 'Adobe PDF' from your list of available printers, then click on the 'Advanced' button.
In the Advanced Print Setup window, locate the 'Color Profile' dropdown menu. Select 'Dot Gain 10%' or 'Dot Gain 15%'.
Click 'OK' to close the advanced settings, then click 'Print' to generate your grayscale PDF.

Modify Paper and Quality Properties
Adjust the default Adobe PDF printer driver preferences to explicitly output in black and white.
Easily Print PDFs in Grayscale with WPS Office
Bypass complex color profile configurations and driver conflicts. WPS Office features a native PDF reader and virtual printer that allows you to print documents or save them in pure grayscale with a single straightforward click.
- 1. Open your document: Launch WPS Office and open the document or PDF you wish to print.
- 2. Access Print Settings: Click on 'Menu' and select 'Print', or simply press Ctrl+P on your keyboard.
- 3. Enable Grayscale: In the print dialog window, check the 'Print in grayscale' box to enforce black and white output.
- 4. Print or Export to PDF: Select your physical printer or the WPS PDF virtual printer, then click 'Print' to finish.

Frequently Asked Questions
Why is the grayscale option greyed out for the Adobe PDF printer?
The grayscale checkbox may be disabled due to conflicts with the source application's native color management, outdated Adobe printer drivers, or specific document security restrictions that prevent color profile modifications.
Why does my PDF still print in color after selecting Black & White in Properties?
Some applications (like web browsers or advanced image editors) bypass the Windows printer properties and send their own RGB color data directly to the virtual printer. Changing the advanced color profile to 'Dot Gain' forces the final output to ignore the source application's color instructions.
Does printing to PDF in grayscale reduce file size?
Yes, converting a color document to a grayscale PDF typically reduces the overall file size because grayscale images only contain single-channel brightness data instead of multi-channel RGB or CMYK data.
