Re: NVDA and OCR software


Hello there,


I am having a problem with the NAPS2OCR addon: when I press ctrl+nvda+shift+r to scan a document from a scanner, nvda announces that the file couldn’t be recognized, though my scanner is plugged via USB to the pc and turned on.


Also, when I press the shortcut key to scan a file and I’m focused on it with file explorer and nvda, it says to wait, that the processing might take a few seconds, and stops there.


What could be causing this?

Thanks for any answer.

Best regards.

The add-on makes the two things...


NVDA+Control+R, in a selected file in File Explorer, makes OCR to the file.

NVDA+Control+shift+R scans a paper document from the scanner...

This is great if you need to scan a document into a PDF.  However, is there any software or hardware/software that will take a PDF with a document that has beeen scanned into the PDF, and make that PDF of the scanned document be able to print.  I can use the windows OCR with NVDA to read the document, but can not print it.  Can you help me here?

Hello everyone,


I do not know if this is a question better suited for the chat subgroup, if it is, please tell me.


If it’s ok to post it here, however, here it goes: if you use any kind of OCR solution that can open and OCR PDFS and acquire images from scanners, what would you recommend for efficient use with NvDA?


If that OCR had the ability to keep the formatting and layout of the document, that would be a much needed extra.


Thanks for any answer.

Best regards.
