Hello Olivier
May not attend a meeting, but do have a suggestion for an amendment to the user guides.
The problem is using a scanner directly from LibreOffice as reported in bug 141507. You can access a scanner from LibreOffice, but only in the Windows version.
macOS version of LibreOffice does not have scanner access because macOS uses the Preview application and this cancels any LibreOffice direct access to a scanner.
Windows version of LibreOffice does have scanner access, but that is limited by the age of the scanner. Some scanners are no longer supported by the manufacturer, for example Canon. This means you can no longer use a propriety scanner application from the scanner manufacturer.
Old scanners can operate using freely available 3rd party applications, but operating through LibreOffice does not work. I have a multi-function printer and a very old flatbed scanner. My flatbed scanner does work using VueScan, but not through LibreOffice.
My suggestion is to remove any references to scanning from the LibreOffice user guides. It is easy enough to scan images or text using scanning software, then import the file into LibreOffice.
What are your views on Bug 141507 and my solution with the user guides.
Regards
PeeWee
