The best grayscale result when printing a PDF in black and white comes from using your PDF application's built-in print settings rather than relying solely on the operating system print dialog. Using a PDF editor that communicates directly with the printer driver—rather than routing through a generic OS print handler—gives you control over contrast, ink density, and page selection. For enterprise printing where ink cost and document consistency matter, configuring default B&W settings through a centrally managed PDF tool eliminates per-user variation.
Print a color PDF in black and white and you might get one of two results:
A clean, readable monochrome document.
Or a muddy, low-contrast printout where colored text disappears and images look washed out.
The difference isn't always the printer. It's often where you apply the black-and-white setting—and whether your PDF application communicates that intent clearly to the printer driver.
This guide covers how to print PDFs in black and white on Windows and Mac, how to print only specific pages in grayscale, and what actually determines print quality.
Why Grayscale Quality Varies
When you print a color PDF in black and white, the printer converts each color value to a shade of gray using a conversion formula. The quality depends on three factors:
1. The conversion method
- Luminance-based conversion preserves perceived brightness. A bright yellow and a bright blue map to appropriately different gray tones.
- Simple desaturation removes color without accounting for brightness—yellows and light greens can become nearly invisible.
Most modern printer drivers use luminance-based conversion, but not all. Older or budget drivers use basic desaturation, producing the muddy output users often blame on paper quality.
Applying black-and-white at the printer driver level is more reliable than applying it in the OS print shortcut. The print dialog inside a dedicated PDF application typically gives more consistent results.
How to Print a PDF in Black and White on Windows
Using LynxPDF RECOMMENDED FOR ENTERPRISE
LynxPDF is a desktop PDF solution for enterprise teams on Windows and Mac. Its print workflow passes B&W settings directly through the printer driver for consistent output.
- Open your PDF document in LynxPDF
- Click Print at the top right, or press Ctrl + P
- Click Attributes
- Go to the Paper/Quality tab
- Under Colour, select Black & White
- Click OK to confirm, then Print
How to Print a PDF in Black and White on Mac
Using LynxPDF
- Open your PDF document in LynxPDF
- Click File at the top left → Print…, or press Command + P
- In the Pages section, select your Printer from the dropdown
- Check the Black & White option
- Click Print
How to Print Only Specific Pages in Black and White
This is one of the most frequently asked questions—and most PDF apps support it with a two-step approach:
In the print dialog, find the Pages or Page Range field and enter the specific pages you want:
- Pages 3–7: enter
3-7 - Pages 1, 5, and 9: enter
1, 5, 9 - All except page 2: print page 1, then 3 to end separately
With the page range set, apply the B&W color setting in the printer properties (same steps as above). This print job will only output the selected pages in black and white.
LynxPDF supports page range selection in its print dialog. You can also use the Print Selected Pages function for more granular control.

Which Method Gives the Best Grayscale Result?
Not all black-and-white output is equal. Here's how the common methods compare:
| Method | Grayscale Quality | Preserves Text | Notes |
|---|---|---|---|
| LynxPDF print dialog → printer driver B&W | ✅ High | ✅ Yes | Recommended for enterprise; consistent output |
| OS print dialog → printer driver B&W | ✅ High | ✅ Yes | Similar quality; less control over PDF rendering |
| Adobe Acrobat Pro Preflight (save as grayscale) | ✅ Highest | ✅ Yes | Best for print production; requires subscription |
| Online converter → then print | ⚠️ Medium | ✅ Yes | Depends on converter quality; extra step required |
| Screenshot / print to image | ❌ Low | ❌ No | Destroys text layer; never recommended |
Five Factors That Improve Grayscale Print Quality
1. Use a PDF application, not the browser
Printing PDFs from a web browser (Chrome, Safari) uses the browser's built-in renderer, which may not communicate color settings as precisely to the printer driver. Use a dedicated PDF application for more reliable results.
2. Keep printer drivers updated
Outdated printer drivers use older color conversion algorithms. Updated drivers often include improved luminance conversion for grayscale output.
3. Choose the correct paper
For laser printers: standard 80 g/m² office paper works well. For inkjet printers printing image-heavy documents: matte photo paper produces noticeably sharper grayscale output.
4. Adjust contrast before printing (if needed)
If the printed grayscale output looks washed out, some PDF applications allow you to increase contrast or brightness in the image settings before printing. This is more impactful than paper choice for image-heavy documents.
5. Print at 600 dpi or higher
Most modern printers default to 600 dpi for documents. For image-heavy PDFs printed in grayscale, setting 1200 dpi (if supported) noticeably improves the definition of photographic content.
Enterprise Use Case: Reducing Ink Costs at Scale
For organizations that print thousands of pages per month, black-and-white printing can reduce supply costs significantly. Color ink cartridges typically cost 3–5× more than black cartridges, and color toner for laser printers is similarly priced.
A team of 50 employees each printing 20 pages of color documents weekly amounts to 1,000 color pages per week. Shifting even half of those to black and white reduces color page volume by approximately 26,000 pages per year.
LynxPDF's Admin Console lets IT administrators:
- Deploy LynxPDF across all devices via GPO, Intune, or SCCM
- Manage licenses centrally, including batch license assignment
- Maintain a standardized print configuration across the organization
This means black-and-white printing policies are enforced consistently—without relying on individual employees to change their own settings.
Frequently Asked Questions
Q: Which method gives the best grayscale result when printing a PDF in black and white?
A: For most office workflows: apply the B&W setting through your PDF application's print dialog, which communicates with the printer driver directly. For print production where color accuracy in the converted file matters: use Adobe Acrobat Pro's Preflight grayscale conversion. For enterprise deployment with consistent output across many users: LynxPDF with centrally configured print defaults.
Q: Can I print only specific pages of a PDF in black and white?
A: Yes. In most PDF print dialogs, enter a page range (e.g., 3-7 or 1, 5, 9) and apply the B&W print setting for that job. LynxPDF supports page range selection alongside B&W output settings on both Windows and Mac.
Q: Why does my black-and-white printout look muddy or low-contrast?
A: This usually means the printer driver is using basic desaturation instead of luminance-based conversion. Try updating your printer driver. If the problem persists, use Acrobat Pro to convert the file to a proper grayscale PDF before printing—this bypasses the driver's color conversion entirely.
Q: Does printing in black and white save ink?
A: Yes, significantly. Black-and-white printing uses only the black ink/toner cartridge, skipping color cartridges entirely. For teams with high print volumes, this is one of the most impactful cost-reduction measures available without changing hardware.
Q: Can I set black-and-white as the default for all users in my organization?
A: With LynxPDF, IT teams can configure default print settings as part of the deployment package (GPO, SCCM, Intune). This enforces B&W printing as the default across the organization without requiring individual setup.
Summary
Printing PDFs in black and white is straightforward—but getting the best grayscale output consistently requires understanding where the color conversion happens.
For individual users on Windows or Mac: use LynxPDF's print dialog with the B&W setting in printer attributes.
For teams: deploy LynxPDF with configured defaults through the Admin Console to enforce consistent black-and-white printing organization-wide.
For specific pages: set the page range in the print dialog, then apply the B&W color setting to that print job.
