Adobe Acrobat is full of bugs!

Hi @PeterBB ,

Hope you're doing well, and sorry to hear about the trouble. 

A few details would help pin down what's going wrong:

1. What OS and Acrobat version are you on (Help > About Acrobat will show the version)?

2. When OCR fails, do you get a specific error message, or does it just not produce any recognized text?

3. Same question for "print to PDF", does it throw an error, freeze, or produce a blank/corrupted file?

In the meantime, here's a path for the TIFF specifically:

1. Open the TIFF in Acrobat (File > Open, and select the TIFF; Acrobat will convert it to PDF automatically).

2. Go to the "Scan & OCR" tool and select "Recognize Text" > "In This File."

3. Once recognized, you can export it as a searchable PDF, or use File > Export To > Word/RTF if you need editable text to bring into Affinity Publisher.

• Make sure the TIFF pages are clear, straight, and reasonably high resolution (skewed or low-res scans are the most common cause of OCR failures).

• Try converting each TIFF page individually rather than all 10 at once, to see if it's a specific page causing the failure.
  
  

For "print to PDF" failing every time, that's often fixed by repairing or reinstalling the Adobe PDF printer driver. I'd be happy to walk through those steps once I know your OS.
