Observed behavior

Solution 1Recommended

Test with an Alternative Physical or Virtual Printer

Isolate the issue to determine if the problem lies with the Adobe PDF printer driver or the source document's field codes.

By routing the print job through a different printer, you can determine if the glitch is a universal rendering issue within your word processor or a specific defect with Acrobat XI's virtual printer driver.

1
Print to a physical office printer

Open your original document. Go to File > Print, select your standard physical printer from the drop-down menu, and print a test copy of the first few pages.

2
Use an alternative PDF printer

If a physical printer is unavailable, select 'Microsoft Print to PDF' from your printer list and execute the print command to generate an alternative PDF.

3
Analyze the output

Review the physical pages or the new PDF file. If the number sign (#) does not appear in the footer, the issue is exclusively linked to the Acrobat XI PDF printer configuration.

Diagnostic Outcome: If the issue only occurs with the Adobe PDF printer, you can bypass it entirely by using native PDF export functions.

Frequently Asked Questions

Why does a number sign (#) appear in my PDF when it is not in my Word document?

This glitch often occurs when dynamic page numbering fields fail to render properly during the virtual printing process, or due to specific conversion conflicts in older software like Acrobat XI.

Does reinstalling Adobe Acrobat XI fix PDF printer glitches?

It can help if the PDF printer driver has become corrupted. You can easily attempt a fix by opening Acrobat XI, going to the Help menu, and selecting 'Repair Acrobat Installation'.

Can I use 'Save As PDF' in Word instead of printing to Adobe PDF?

Yes. Using the native 'Save As' > 'PDF' or 'Export' function in your word processor bypasses the Adobe PDF virtual printer entirely, which usually prevents these unexpected rendering errors.

Is Adobe Acrobat XI fully compatible with Windows 10?

Adobe Acrobat XI is an older, end-of-life version of the software. Because it is no longer supported, occasional compatibility issues, such as virtual printing glitches, may occur on modern operating systems like Windows 10.
