Converting different formats to PDF in calibre i set values for margins in Preferences/ Common Options/Page Setup but in the output file top and bottom margins disappear. How can i fix it?
What version are you using?
the latest, i think 0.7.43
I've solved the problem : i uninstalled the latest version (0.7.43) and installed an older one (0.7.31) and now everything is ok. Evidently it is a bug in (0.7.43).
Please open a ticket and include the versions it worked and stopped working in. That way I don't lose track of this issue. I don't have time at the moment to devote to looking at what changed and caused it to break but I would like to correct it in the future.
