How to Fix Low-Resolution or Pixelated PDF Printing
Question details
The user is trying to determine why a PDF prints in low resolution or appears pixelated on one computer but prints perfectly fine on another.

- Device & OS

- Scenario
- Printing a PDF document, often created in professional design software, and collaborating with colleagues who are printing the same file from different computers.
- Observed behavior
- The printed document outputs with pixelated or low-resolution graphics on a secondary computer, indicating an issue with local print settings, the PDF viewer, or the print driver rather than the file itself.
Before modifying advanced settings, ensure that your printer drivers are up to date and try opening the document in a dedicated desktop PDF viewer rather than a web browser, as browser viewers can sometimes degrade print quality.
Disable the "Print as Image" Feature
Disabling "Print as Image" ensures the PDF viewer renders text and vectors sharply rather than converting the entire page into a low-resolution graphic before sending it to the printer.
When a PDF is printed as an image, the viewer bypasses the printer's native font and vector processing. If the default resolution for this feature is set too low, the result will be noticeably pixelated.
Open your PDF file in your default desktop PDF viewer. Go to the File menu and select Print, or press Ctrl+P on your keyboard.
Look for an "Advanced" button located near the top or bottom of the Print window and click it to open advanced printer settings.
Locate the "Print as Image" checkbox and ensure it is unchecked. If you are forced to use this setting due to printer errors, make sure the resolution dropdown next to it is set to at least 300 DPI.
Click OK to save the advanced settings, then click Print to test the output.
Adjust Printer Properties and Quality Settings
Sometimes the printer driver defaults to a "Draft" or "Eco" mode, which intentionally reduces print resolution to save ink and speed up the printing process.
Use WPS Office for High-Quality PDF Printing
WPS Office provides a powerful built-in PDF reader that ensures high-fidelity printing for text, vectors, and images without complex setup. It accurately preserves the resolution of your original documents and avoids the pixelation issues common in basic viewers.
- 1. Download WPS Office: Download and install the free version of WPS Office from the official website.
- 2. Open Your PDF: Right-click your pixelated PDF file, select "Open with", and choose WPS Office from the list.
- 3. Open the Print Menu: Click the Print icon in the top toolbar or press Ctrl+P to open the print dialog.
- 4. Print with High Quality: Ensure your page size is correct, select your printer, and click Print. WPS Office will process the vector and image data natively for a sharp output.
Frequently Asked Questions
Why does my PDF look blurry when printed but sharp on the computer screen?
This usually happens if your printer is set to a low-resolution draft mode, or if the "Print as Image" setting is enabled in your PDF viewer with a low DPI limit. Screen resolution is much lower than print resolution, so an image that looks fine on screen may lack the data needed to print sharply unless printer properties are set to High Quality.
Do I need the original Photoshop or Illustrator files to print a PDF clearly?
No. A properly exported PDF embeds all the necessary fonts, vectors, and high-resolution image data. If the PDF is pixelated upon printing but fine on other computers, the issue lies in the local print settings or the PDF viewer being used, not missing linked files.
Can third-party PDF viewers affect print quality?
Yes. Basic or browser-based PDF viewers sometimes fail to process complex high-resolution graphics and vectors correctly when rasterizing the data for the printer. Using a dedicated PDF application like WPS Office or Adobe Acrobat is highly recommended for professional print outputs.
