I don't know enough about this subject to be sure that what I am
saying is correct but raising the questions may be of benefit.
Is this add-on too limited? Does it specify only WIA, or is that
the result of how the scanner itself is already set up to
communicate with the computer? I wonder if the scanner doesn't work
with the add-on because the scanner isn't set up to use WIA.

I have only just gotten around to trying this add-on. I am running
the latest version of NVDA with Windows 10 21H2. My scanner works
fine with other programs such as windows fax and scan and
DocuScan. However when I try to scan a page from the scanner with
this add-on, I receive the following error.
TesseractOCR dialog Scan error
Process wia-cmd-scanner failed:
Scanning to file C:\Users\Mobeen (dpi = 300, color mode 'GRAY',
output format 'JPG')
Exception occured: Access is denied. (Exception from HRESULT:
Please make sure your scanner is WIA-compliant and can scan in
another application before trying again!
I am then prompted if I want to scan another page. When I click
no, the program keeps beeping with no way to cancel the process
until NVDA is restarted. This is quite annoying. Is there any way
around this error? Also in the next version, could you please
consider adding a cancel keystroke or cancel button in a window?
It would be a real shame if the only way of cancelling a scan job
was to restart NVDA. As far as I know, I have all of the relevant
drivers installed. It sounds like the add-on is not running with
admin privileges or isn't able to save and process the image.
Very best wishes,
