- Update Printer Drivers: Outdated printer drivers are a common cause of printing errors.
- Flatten PDF: If the PDF has multiple layers e.g., annotations, form fields, “flattening” the PDF saving a copy without layers can sometimes resolve display or printing glitches.
Incorrect Orientation/Scaling:
- “Fit to Page” vs. “Actual Size”: Ensure your print settings are correct. For patterns or documents requiring precise dimensions, choose “Actual Size” or “100% Scale.” For general documents, “Fit to Page” is often fine.
Font Issues:
- Embedded Fonts: PDFs are designed to embed fonts, but sometimes this fails. If you see “jumbled” text, the font might not be properly embedded. Re-create the PDF, ensuring fonts are embedded.
- Missing Fonts: If you’re editing a PDF and don’t have the original font, the software will substitute it, which can alter the layout.

Dealing with Corrupted or Password-Protected PDFs

Encountering a corrupt file or a forgotten password can be a roadblock.

Corrupted PDFs:
- Try Different Viewers: Sometimes a PDF viewer might struggle with a file that another viewer can open. Try opening it with Adobe Acrobat Reader, Foxit, or even your web browser.
- Online Repair Tools: Several online services claim to repair corrupted PDFs. Use these with caution, especially for sensitive documents, as they require uploading your file.
- Check Original Source: If possible, try to get a fresh copy of the PDF from its original source.
Forgotten Passwords:
- Password Reminders/Records: If you set the password, try to recall if you have it noted down securely.
