Hi Telesto,
if you want to use 300 dpi, should you use TIFF instead of JPEG ? not sure whether it's a LibreOffice use or a limitation in the format itself...
Comment 3 Regina Henschel 2019-12-11 17:41:30 UTC 
Hi Telesto, after you have set the resolution, you need to set the size too.
Comment 4 andreas_k 2020-03-03 22:42:32 UTC 
This is stupid the default dpi should be 300 instead of 96 (we are not in the 90's any more). And the default jpg compression is 80.
