Solving Acrobat Reader PDF Printing Issues with Unicode Fonts

Have you ever encountered the frustrating issue of Acrobat Reader not printing PDFs containing embedded Unicode fonts? If you're currently facing this problem, you’re not alone. This article will explore the root cause of this issue, how to identify the problem, and provide a solution using ReportLab or similar free PDF creation tools.

The Problem With Embedding Unicode Fonts in PDFs

When working with Unicode fonts in PDFs, especially when trying to print them through Acrobat Reader, you may run into several issues. One common problem is that the font embedding may be incorrectly handled, leading to non-printable PDFs. This can be particularly vexing if you rely on precise font rendering across different platforms.

For example, when using a PDF tool that supports Unicode, you may find that the font is embedded as TrueType. However, when opening and saving the same PDF with a different tool like macOS Preview, the PDF becomes more printer-friendly, embedding the font as CIDFontType2. This difference in behavior can be confusing and frustrating.

Understanding Font Embedding in PDFs

In the world of PDFs, font embedding plays a crucial role. Most poor PDF libraries embed fonts as CID-Type 1 fonts. This can lead to rendering issues and, ultimately, non-printing PDFs. However, Adobe Acrobat Reader correctly interprets and prints fonts embedded as CIDFontType2.

To better understand the issue, you can use a tool like PDFlib’s free Font Reporting Tool to generate a full font report of your PDF. This report will provide you with valuable insights into the font embedding within your document, potentially revealing any anomalies that may be causing the printing issues.

Troubleshooting Techniques

Here are some steps you can take to troubleshoot and resolve the font embedding issue in your PDFs:

Check the Font Embedding Type: Use the PDFlib Font Reporting Tool or a similar tool to identify the type of font embedding used in your PDF. This will help you determine whether the font is correctly embedded for printing.Use a Free PDF Creation Tool: If you are creating PDFs for printing, consider using a tool like ReportLab or a comparable free PDF creation tool. Reports indicate that these tools often produce more printer-friendly and correctly embedded PDFs, especially when dealing with Unicode fonts.Test with macOS Preview: As mentioned earlier, macOS Preview often seems to handle Unicode fonts better. If you can, open and save your PDF with macOS Preview to see if the issue is resolved. This can give you an idea of what settings or steps are necessary to create a printable PDF.

Ensuring Printer-Friendly PDFs

By ensuring your PDFs are correctly embedded with the right type of fonts, you can avoid printing issues in Acrobat Reader. Here are some best practices:

Always use a tool that supports CIDFontType2 embedding, such as Adobe Acrobat Pro or a high-quality free alternative.Test your PDFs across different tools to identify and resolve any font embedding issues before finalizing your the Font Reporting Tool to identify any anomalies in your PDF’s font embedding.

Conclusion

Dealing with Unicode fonts in PDFs can be a challenging task, but with the right tools and techniques, you can ensure that your documents are printer-friendly and consistently rendered across different platforms. By understanding the differences in font embedding types and using the appropriate PDF creation tools, you can avoid the frustration of Acrobat Reader printing issues.
